Thanks everyone for your answers, unfortunately i don't feel like starting to swap out computers in the car just to get my spotify going, especially not when i have to find a Camaro PDIM. Although i guess the Sonic PDIM is way easier to find hehe.
Anyway i've found a used iPod touch on ebay which i've rooted and installed spotify including Music Controls Pro. That last thing is promising to get native external control of the ipod although it's running a completely different music app. Well everything works smooth on the ipod but when i connect it to the car the infotainment system says "No supported file format on the iPod". I've searched and searched without results and i wonder if anyone know how to trick the infoatinment to think that it's a regular iPod with files playing instead of the spotify app? Or is this an impossible mission since the Spotify saves in ogg vorbis?
Edit: Success!! With one song loaded to the iPod as a standard mp3 file i managed to trick the infotainment system. As soon as it finds the ipod it plays back the mp3 file, and all i have to do is to start spotify instead and start a playlist. The title and artist shows up on the infotainment, the steeringwheel controls (both volume and skip song) works, it charges and everything. Only issue is that it disconnects if i skip songs too often, a problem which is less frequent if i run Spotify for iOS 4 instead of the newest one.
