Is it possible to install an aftermarket digital phone car kit(Sprint PCS)and be able to use the phone features offered for the analog phone (ie: steering wheel controls, mute mode etc)? Would there have to be any wiring modifications?
: The US is a patchwork of 3 different digital air interface standards (IS-136, IS-95, and GSM) operating in 2 different frequency bands. (800 MHz and 1900 MHz) Each cellular or PCS carrier is free to choose which standard they want to use. Only good old AMPS analog is truly ubiquitous. BMW would have to offer a lot of different permutations of dual-mode and dual-band phones to cover every US cellular carrier. OTOH, the entirety of Europe is covered by GSM digital, which is government mandated, so BMW can offer one digital phone that works everywhere.
: IMO, getting a built in phone in the US cellular market is a waste of money. Your local cellular carrier has a lot of niftier portable phones that work with their digital systems.
: Perhaps, BMW could work out some sort of deal with someone like AT&T Wireless or Sprint PCS, who have nationwide coverage. This is the only way I see this working.
