any head unit(i have an Alpine...and i like it) that has bluetooth and iPod capabilities should work...although, as of right now, in order to use both, you need to answer "NO" for airplane mode when it asks...when this happens, you will get interference through your speakers from the iPhone(unless your equipment is shielded properly), which stinks, but if you turn the radio volume up(which we all should do!!), it will drown out the interference...if you choose "YES" you lose the bluetooth function and you cant use it as a phone
