My understanding is that the SOS button uses the standard stereo to allow the SOS operator to talk to the driver using a combination of the stereo's hands-free system and the CAN bus. If a non-standard stereo is put in the car it seems most unlikely that comms with SOS will still work, though I would expect that the SOS operator would still get your basic car details and location using the iOn's built in GPS/telematics system... I don't know this for sure but I emailed Peugeot some months ago and reading between the lines of their rather cryptic reply... such was my understanding. MW
