Subaru Android Auto Upgrade: What’s Possible, What’s Not & What Actually Works

CherishYourCar.com is reader-supported. As an Amazon Associate, we earn from qualifying purchases.

If your Subaru doesn’t have Android Auto—or only supports it through a wired USB connection—you’re probably fed up with limited features or clunky setups. Navigation, hands-free texting, voice commands, streaming apps—they’re no longer luxuries, they’re daily driving essentials.

Subaru started offering Android Auto across most trims around 2019, but if you drive an older model or one with a vertical screen, you’ve likely run into dead ends trying to get it working the way it should.

This guide breaks down all your upgrade options. From free software patches to plug-and-play wireless dongles to full head-unit replacements, we’ll walk through what works best for your model year, what’s worth the money, and what to avoid altogether.

1. Factory Support Isn’t Always Enough—Here’s What Subaru Actually Offers

Most 2019 and Newer Subarus Come Ready to Go

Starting with the 2019 model year, Subaru began including Android Auto as standard on most trims. If you’ve got a 2019+ WRX, Outback, Ascent, Crosstrek, or Legacy, chances are your vehicle already supports wired Android Auto straight out of the box.

Some of the newest models, like the 2025 Outback and the all-electric Solterra, even include wireless Android Auto—but usually only on higher trims. For everyone else, it’s USB-only, which means your phone needs to be physically plugged in every time.

Software Updates Can Help—but Only If You’re Lucky

Subaru has released a handful of infotainment updates over the years. The most notable one? A firmware patch for 2020–2023 models with vertical screens (like the Outback, Legacy, and WRX). This update enables full-screen Android Auto, which had previously been limited to a small upper portion of the display.

Here’s the catch: not all updates are available OTA (over the air). Some need to be done manually using a USB stick, and others may require a trip to the dealership, which might come with a labor charge depending on your warranty status.

What Subaru Won’t Do for You

If you own a Subaru made before 2019, you’re out of luck when it comes to official upgrades. Subaru doesn’t offer any retrofit kits or in-house options for adding Android Auto to older head units. That means if your car didn’t ship with it, you’ll need to look at aftermarket solutions or third-party workarounds.

2. Ditch the Cable: Turn Wired Android Auto into Wireless

How Wireless Dongles Actually Work

If your Subaru already has Android Auto but it only works when plugged in, a wireless dongle is your easiest upgrade. These small USB-powered devices plug into the same port you’d normally use to connect your phone.

Instead of a cable, they create a wireless bridge via Wi-Fi and Bluetooth, tricking the car into thinking your phone is physically connected.

No tearing apart the dash. No expensive install fees. Just plug it in, pair your phone, and you’re good to go.

What You Can Expect to Pay

The price range is surprisingly wide. Budget-friendly options start around $70, while premium picks with better chipsets, faster boot times, and OTA firmware updates can cost up to $300. Some of the most trusted options for Subaru include:

• Motorola MA1 – Reliable and widely supported

• AAWireless – A fan favorite for Android users who want regular updates

• CarlinKit 4.0 – Works with both Android Auto and Apple CarPlay

If you’re on a 2020 Outback, 2023 WRX, or even a 2019 BRZ, these plug-and-play options are all compatible.

Pros and Cons You’ll Actually Notice

Here’s the upside: it feels seamless. Once paired, your phone connects automatically every time you start the car. No cables, no fumbling.

But it’s not flawless. Some users report minor lag, particularly in audio streaming or during phone calls. A few dongles may need occasional reboots, and firmware updates aren’t always as smooth as promised.

That said, for most people, the trade-off is worth it. If you hate plugging in your phone every drive, a dongle is the easiest fix.

Confirm Your Subaru Is Compatible

If your car has factory-wired Android Auto, a wireless dongle will likely work. This includes:

• WRX (2019–2025)

• BRZ (2022–2025)

• Outback, Legacy, Ascent, Forester (2020–2024 trims with Starlink and Android Auto)

• Crosstrek Hybrid and Limited (2020+ with 8-inch screens)

If your Subaru doesn’t already support Android Auto with a cable, no dongle will magically add it—you’ll need a full head-unit replacement (that’s up next).

3. Head Unit Swaps: The Ultimate Android Auto Upgrade

The Best Fix for Pre-2019 Models (and Control Freaks)

If your Subaru doesn’t have Android Auto—or you’re tired of the tiny factory screen—a head unit replacement is the most powerful route. This is especially true for 2013–2018 models like the Outback, Forester, Impreza, and WRX, which never got Android Auto from the factory.

Swapping in a modern head unit means you’re not just adding Android Auto. You’re unlocking wireless connectivity, faster processors, bigger displays, and features like built-in DSPs, iDatalink Maestro support, and even 10-band EQs.

In short: your infotainment system stops feeling like it’s stuck in 2014.

Top Brands That Subaru Owners Swear By

Some aftermarket units are built for universal use, while others are Subaru-specific with harnesses that let you skip the splicing:

Brand Subaru-Specific Model Screen Size Wireless AA Est. Price Notes
Sony AX4000 Universal fit 6.95″ $350 Shallow chassis, great reliability
Pioneer W4660NEX Universal fit 6.8″ $600 HD Radio, iDatalink-ready
iDoing 9″ Outback 2015–2019 9″ $450 Plug-and-play for Subaru harnesses
Joying 10.1″ Forester 2016–2018 10.1″ $400 Android 13 OS, tablet-like experience

These aren’t just random eBay specials. iDoing and Belsee, for example, are known in Subaru forums for offering full kits that retain steering wheel controls, factory cameras, and premium audio integration.

Watch Out for These Model-Specific Quirks

Subaru’s infotainment quirks aren’t always obvious until you’re knee-deep in trim panels. Some common surprises:

• Harman Kardon audio? You’ll need a dedicated amp turn-on wire or RCA adapter.

• Factory backup camera? It likely runs on 6V, but most aftermarket units output 12V—so you’ll need a reducer.

• Starlink module? It can block fitment in some 2016–2018 Crosstreks and Imprezas—double-check clearance.

DIY vs. Paying a Pro: What to Expect

If you’re comfortable with tools and don’t mind pulling some dash panels, installing an aftermarket head unit can be a solid weekend project. Most plug-and-play kits include everything you need—mounting brackets, custom wiring harnesses, and sometimes even camera adapters.

A DIY install won’t cost you anything beyond the parts and usually takes about 2–4 hours, depending on your experience.

Going with a professional install typically runs $150–$300 for labor, especially if you need amp integration or a Maestro flash to retain factory features.

One 2015 Forester owner reported saving nearly $900 by installing an iDoing unit themselves, including keeping the factory camera and Bluetooth mic fully functional.

4. Watch for These Compatibility Hiccups Before You Buy

Vertical Screens Aren’t Fully on Board (Yet)

If you’ve got a 2020+ Outback or Legacy with that sleek 11.6″ portrait-style screen, don’t expect full-screen Android Auto out of the box. These head units often display Android Auto in a shrunken window, using only the top portion of the screen.

Subaru has rolled out firmware updates (notably v.AGU‑23.XX and up) that finally allow full-screen support, but you’ll likely need a dealership flash or USB update. Owners on Reddit report success—but only after multiple rounds of updates.

And here’s the kicker: Apple CarPlay often works full-screen without the extra hassle, which just adds to the frustration for Android users.

Older Subarus Come with Hardware Headaches

If you’re rocking a 2008–2012 Subaru, your dash opening and wiring won’t match modern double-DIN units out of the box. You’ll need a custom trim kit, a separate Bluetooth mic, and often a backup camera workaround just to make things functional.

It’s not impossible, but it’s not plug-and-play either. If you’re not comfortable with splicing wires and chasing power sources, budget for a pro install—or consider going with a newer factory-style unit like those from iDoing or Joying.

Harman Kardon Systems Can Get Touchy

Subarus with the Harman Kardon premium audio system add another wrinkle. These systems often require a high-level input adapter or RCA converter to avoid blasting your amp—or worse, frying your speakers.

Some head units don’t output the clean signal these amps need, and skipping the right interface can kill sound quality or cause distortion. If your Subaru has HK audio, double-check compatibility and look for units that specifically note HK support in the specs.

Common Troubleshooting Paths That Actually Work

Running into Android Auto issues after the install? Here’s a simplified cheat sheet of what most owners do:

• No connection at all? Try a different USB cable—cheap ones are often the culprit.

• Funky audio lag or freeze-ups? Clear the Android Auto cache on your phone and reboot both devices.

• Display not showing AA? Go into your head unit’s settings and manually enable Android Auto.

• Still not working? Factory reset the infotainment system or flash the latest firmware from the dealer.

5. What’s It Gonna Cost You? A Real-World Breakdown

Firmware Patches: Cheap, If You’re Lucky

If you’ve got a 2020–2023 Subaru with a vertical screen (like the Outback or Legacy), you might just need a dealer firmware update to unlock full-screen Android Auto. Some owners have done it for free via USB at home, while others paid the dealer $80–$120 for the flash.

However, this only applies to a limited group of models. If your car doesn’t already support Android Auto, Subaru won’t retroactively add it—period.

• Estimated total: $0–$120

• Best for: 2020–2023 models that already have Android Auto

• Drawback: Only helps with screen layout—no new AA for older head units

Wireless Dongles: No Head Unit Swap Required

If your Subaru already has wired Android Auto, this is the easiest path to a cable-free life. Devices like the Motorola MA1 or AAWireless plug into your USB port and trick the car into thinking your phone is plugged in.

They’re dead simple, but not flawless—expect the occasional lag or glitch, especially on longer drives.

• Price range: $70–$300

• Best for: 2019+ Subarus with factory Android Auto

• Drawback: Slight delay, can feel glitchy with certain head units

Aftermarket Head Units: Big Upgrade, Bigger Price Swing

This is where you open up the options—and the budget. For cars that didn’t come with Android Auto at all, or if you want wireless AA, a larger screen, and better sound, this is the way to go.

You’ll find:

• Mid-range units from Sony or Pioneer: ~$350–$600

• Subaru-specific units from iDoing or Joying: ~$400–$500, often plug-and-play

• High-end “Tesla-style” screens: $750–$1,200 installed, but they can block vents or look overly flashy

Labor? DIY install saves you $150–$300, but it’s not for the faint of heart. Crosstrek, WRX, and Forester owners with premium audio should plan ahead for amp and camera quirks.

The Big Leap: Just Buy a New Subaru?

If you’re driving a 2013 Legacy or 2010 Outback and dreaming of wireless Android Auto with a modern screen, you might wonder if it’s worth trading up entirely. The answer? Sure—but only if you’re already shopping for a newer car.

• Cost: $30,000+

• Drawback: You’re paying for way more than just Android Auto

• Upside: You get it factory-installed, under warranty, and fully integrated

6. Real-World Feedback from Subaru Owners Who’ve Upgraded

iDoing Wins Big with DIY Subaru Fans

If there’s one name that pops up again and again in Reddit threads and YouTube installs, it’s iDoing. Owners of 2015–2019 Outbacks, WRXs, and Foresters consistently call it a plug-and-play winner.

The interface is fast, it keeps factory features like steering wheel controls, and the harnesses are often tailored to specific Subaru models, saving hours of guesswork.

But it’s not without a catch. Some users with Harman Kardon systems had to reroute amp power wires, and factory backup cameras sometimes needed voltage reducers to match 6V-to-12V differences.

Still, for DIYers, the savings were real. One Forester owner bragged about saving $900+ versus a shop quote by installing it in their driveway.

Wireless Adapters: Convenient, But Not Always Snappy

Those jumping to wireless AA with a dongle love the no-cord life—until lag hits. Users of the Motorola MA1, AAWireless, and OneCar AI box praise their setup… when it works. But some report a few-second audio delay or needing to unplug/replug after software updates.

That said, if your car already supports wired AA, this is still the lowest-effort upgrade. Setup is usually a one-time thing, and for most people, the cable-free convenience far outweighs the quirks.

Budget Android Units: A Mixed Bag at Best

It’s tempting to grab a $150 Android head unit off Amazon. Brands like OiLiehu, Roadanvi, and SYGAV offer giant screens and flashy Android interfaces, often claiming Subaru compatibility. But in practice? Some users regret it.

Common complaints include:

Buggy Bluetooth

Weak audio output

Poor touchscreen responsiveness

Mismatched harnesses that fry factory amps

Forums like XDA are packed with cautionary tales—many suggest saving up for a trusted brand or at least checking for known install guides before ordering.

Subaru’s Software Updates? When They Work, They Work

If you own a 2020–2023 Outback or WRX with the vertical screen, and you’re still seeing half-screen Android Auto, you might just need the latest firmware. Redditors confirmed that version AGU-23.xx or newer enables full-screen AA.

One 2022 WRX owner said the update made Android Auto “actually usable” and avoided the need to swap head units entirely. But results vary—some dealers charge for the flash, and some users had to load it manually via USB.

So yes, factory support exists—but don’t expect Subaru to retroactively offer full Android Auto to 2015-era cars. That ship has sailed.

7. Which Route Is Right for You? A Practical Checklist

Start with Your Model Year

This is non-negotiable. If your Subaru is 2019 or newer, chances are you already have wired Android Auto. That opens the door to simple upgrades like wireless dongles. If it’s pre-2019, you’re likely looking at a full head unit replacement.

Not sure? Check your owner’s manual or plug your phone in—if nothing happens, you’re in aftermarket territory.

Know What You Actually Need

Ask yourself: Are you just tired of cords, or are you completely missing Android Auto?

Just want wireless? Get a dongle.

Missing Android Auto altogether? You’ll need a head unit swap.

Also consider how often you use navigation, calls, or music apps. If your phone is the command center of your commute, Android Auto isn’t a luxury—it’s a must.

What’s Your Budget?

Here’s the rough scale:

• Under $100: Wireless adapter (if your system supports it)

• $300–$600: Reliable aftermarket head unit

• $600+: Tesla-style screen, DSP audio, wireless AA—all the bells and whistles

Don’t forget to factor in installation tools or professional labor if you’re not doing it yourself.

Retaining Factory Features? Do Your Homework

Make a list before you buy:

Steering wheel controls

Backup camera

Harman Kardon or Bose sound

STARLINK module

If you want to keep these intact, you’ll likely need extras like iDatalink Maestro or plug-and-play harness kits. Subaru models are picky—don’t assume your features will “just work” out of the box.

Look for Documented Installs of Your Subaru

Before you order, search YouTube or Reddit for someone with your exact model and year. If a 2016 Forester owner installed the same unit you’re eyeing, that’s a good sign. Bonus points if they list what wiring kits they used or any quirks they hit during install.

Wrapping It Up: What to Know Before You Pull the Trigger

If your Subaru already has wired Android Auto, a wireless dongle is the fastest win—just plug it in, pair your phone, and enjoy the convenience.

For older models without Android Auto, a head unit swap is your best path. Brands like iDoing or Pioneer offer Subaru-friendly kits that retain your camera, steering wheel controls, and even premium audio with the right harness.

The key is choosing hardware that’s actually compatible with your model. Some systems need a voltage reducer or amp trigger wire. Others may require a Maestro module to keep everything functional. Skip generic Android head units—they’re cheap for a reason and often bring lag, bugs, or Bluetooth issues.

For most people, it’s about balancing the budget with reliability. If it connects cleanly, runs smoothly, and looks factory once installed, you’ve nailed it.
