I have a Volvo S40 2005, with the basic audio system without CD-changer.
I want to upgrade this to an 2006 high performance, not the speakers, just the main unit to be able to extend it with an AUX, USB and Android/iPhone connector.
Is this upgrade possible?
Okay, i tried the GROM box, and it didn't work. I got special made software for the grom box too, but no results. Anyone who knows if it's possible to upgrade to the high performance unit, and if thats possible, how to upgrade? Then i can use the CDC port and buy a dension 500 or something...
