So, I'm thinking of upgrading the radio in my 407sw. It just has the basic RD4 factory fitted radio with the orange screen that goes black as soon as the heating goes on.

I'm wondering, if I buy one of the Android touchscreen radios:
Will I lose the functions on the original radio, like setting the time, air conditioning display and options like single\dual control etc? Or can I control them from an Android stereo?

And other things like auto-headlights, temperature, and other various options on the RD4?

I assume I'll also have to get an adapter cable.

Bonus questions:
Will I be needing some sort of bracket for an exact fit?
Isn't it kind of silly having the old radio still sitting in there if it's no longer being used?

Or would I be better off getting a used RT3 with all the bells and whistles?

It's 2006 so I'm also thinking about how long before it goes to the scrapyard..

Has anybody installed an aftermarket Android stereo? Or one of those cheap mirror-link ones?

I wouldn't bother with an RT3 unit. You won't be gaining much functionality. The maps runs off a disc making it slow.

RT4/5 would be better due to the much better looking screen and hard drive based maps along with speed cameras, however with the age of these, both the RT3/4/5 only have maps until Q4 2015.

Both of these options will be a pain in the ass for you. You will need to figure out the GPS sensor location and wiring etc

I am currently looking to either upgrade my RT4 to an android chinese headunit or hopefully get the small screen and vehicle functionality working with an adaptor and a Alpine/Sony etc headunit.

With a generic android headunit, you will lose ALL vehicle controls (HVAC, Parking assist, Headlamp control etc).

You would need a custom Android headunit made for a 407 which is largely plug and play to retain some of these functions....however it can be hit or miss and I haven't found one that looks OEM and integrates all OEM functions perfectly.

Do you know if you can get any of these functions back using a bluetooth OBD tool, and torque, or some other app? I know you can get some info to the display, like revs, speed, etc.
Depending on how it goes I might try and cut up the old frame to fit the Android into it, or get one 3D printed to fit. Or, hell, I might just buy a 3D printer. Been meaning to for a while anyway.

The factory systems are old now, and for some maps have now been discontinued.

Off-the-shelf I'd be looking at something like this
CES AUTOS Limited. Peugeot 407 Android 8.0 V5588

For a DIY-tablet job I reckon you'd need to:
* be an Android developer
* reverse engineer Peugeot's CAN bus commands and responses.
(I am working on these.)

Maps have been discontinued on all the factory systems for 407. RNEG is the only one you can get 2016 maps for but that's it, no further.

How far have you gotten on your journey? I would be interested in a custom system too.

If you look at Aliexpress and specify peugeot 407 there are android units to fit the 407 specifically with the can bus interface supporting aircon and other controls etc.

You may have to play with the built in equaliser to make the sound output equivalent. It might sound a little empty otherwise as manufacturers spend time and money making the stereo output good for vehicles these days.

So the stereo I ordered (link above) arrived a few days ago. And I half installed it but I still have some issues to sort out:

  • Need to get a fascia for it, or cut up the factory one to fit the screen in.

  • Need to get a radio antenna adapter. Think they're called Fakras

  • Need to get the steering controls working
I tried connecting the "keys" wire from the stereo to one of the can buses on the radio harness, and the car started doing really weird stuff. The rev counter and fuel gauge started jumping around the place, there some was beeping noises, and general mayhem.

I know there's can bus adapters available alright. Might pick one up in the future, maybe. I'd be interested to know how you're working on the can signals? Hardware? Software?

My initial thoughts were that something like this should be easy to integrate into an Android app. Just record each signal, and then map it to a function in the app. But I assume there's more to it than that, or someone would have done it already!


Besides these issues it's all working fine, gps navigation, music etc. The unit also boots up relatively quickly (10-20s) and is quite quick and responsive. It also includes a reverse camera. Not bad for £60.

DO NOT plug any random wire to the canbus...unless you are 100% certain you know what you are doing. Best case scenario... some stuff stops working. Worst case, get ready to replace the BSI, ECU, Dashclocks, Door ECU's, wiper motors etc etc. The canbus is literally the connection between ALL ecu's in the car. (some connect over LIN but that's different)

It is just that simple, ECU's "talk" to other things by introducing commands into the canbus, something like #12345678

The Hashtag is the start of the message, the first number is what ECU it needs to go to, the rest is the coded message. (simplified explanation but it's actually a bit more complex with error correction algorithms)

If you get a hardware device that can introduce the right commands onto the canbus and read codes from other ECU's, you've done it.... you can easily buy this anyway using something like an arduino with a shield.

The other half of the work is knowing which messages are needed and WHEN.

Oh and of course, coding an Android app that can display the data.
