My son has an Infinity system on 1500 Ram Truck 2003. Cd player isn't working and he wants a new unit that is IPOD capable. Truck has sound controls on steering wheel. Have been given conflicting information on whether or not (or how well) an after-market will work with the infinity speakers (7 speakers) and steering wheel controls.

Anyone have any suggestions or advice on a unit that will a) work with the speakers, b) IPOD capable, c) work with steering wheel controls d) all of the above?

Talked to Crutchfield and they suggested Alpine 9856 but total on that (without installation) is over $350 and you have to buy a remote to "teach" steering wheel to work with the radio.

Thanks!
