Hey everyone! I have a 2012 R57 S with a regular (non HK) Boost CD radio system. I successfully installed a double DIN aftermarket radio with CarPlay/Android Auto thanks to all the folks on this forum.

I've read on other threads here that certain scans (DIS, ISTA) and dealer diagnostics/updates require the OEM radio to be present.

To make this easier, I was wondering if there's some way I can have both radios connected to the CAN bus. It's simple to tap the wires, but the question is SHOULD I?

I called techs at both Crutchfield and Metra/Axxess and all said I'm in uncharted waters. Metra has done this before on Cadillacs, but never on European cars.

Not sure if I should even experiment doing this. Plan B is to wire up my own harness to glovebox so that it's easier to switch between the two radios. Any thoughts most appreciated!

 

So what was the outcome with the wiring.......how did you accomplish the install...

 

At the moment I just have the aftermarket radio connected using the Axxess LC-BMRC-01 wiring harness, and the OEM radio is disconnected

 

Ohhhhh.......okkkkay glad you have positive results...

 

Thanks! I'll post pics and stuff in another thread later.

If anyone has ideas on my original question though, about the risk/safety of wiring both radios on the CAN bus at the same time, most appreciated!
