Quick question for any would-be Nokia genius out there. I have a Nokia car kit (CARK-91 for the 6210, 6310, etc). I also have a Nokia 3200 that I'd much rather use as my main phone in place of my 6210. Nokia seem to supply a cradle for the 3200 (mbc 15s - they sell it separate to the usual car kit for the phone). My question is what are my chances of this cradle being the only thing I need to upgrade my car kit to handle my 3200 given that the wires are only microphone, antenna, power, and speakers. Can't be that different, can it??? Any thoughts would be appreciated as I'd really like to simply change the cradle without having to hand over a large amount of cash to solve what seems like a very simple problem.
