Actually there are two cradles available for iPhone 3G, #84212151043 & 84212151038.
Do you have Smartphone Intergration installed?
Because part #84212151043 will only work if you have Smartphone Integration installed,
It will charge, play music and improve cellphone signal.
Otherwise you need to get part #84212151038 which will only improve your cellphone signal and charge your phone,
No iPhone control via steering wheel or play music from iphone.
