i know it says you need iphone 4 and up, but i'm using 3Gs until i upgrade to the 4Gs. From what i noticed i'm able to use Pandora, iTunes, and the phone functions. The only thing i cant do is click on the apps icon on the main screen of the actual app radio unit. when i click on it i get the black screen of death. is that normal because i have a 3Gs? or has it been a problem for you 4G users as well? sorry i don't have an 4G to test. also the only reason i can use pandora is by clicking on it viva iphone and it does show up like normal on the pioneer screen with all the functions.

Hi, on 4g it works... I suppose it is only a 3GS problem.
