HI folks, I sit here typing this after some real madness trying to get our new 2008 335xi hands free phone service up and working. When we bought the car our salesman paired up our T-Mobile Dash cell phones to the car and initially it appeared to work wonderfully! Incoming and outgoing calls worked like a snap. But the street addresses did not come over from the phones for the Nav System so that we could use the Nav system to direct us to an address in the phone book. Seemed odd but certainly not a show stopper - I can mention it to the service dept when I bring the car in for its upgrades. When I brought the car in to get satellite radio and the alarm system installed I mentioned this to the service rep and he asked what cell phones we are using and he told me we were NOT using BMW approved phones. "Approved Phones"??!!! HUH????!!! Not only that but if we continued to use these phones we run the risk of corrupting the computer and a $1,200.00 repair bill!!! YIKES!! The salesman most assuredly should have been MUCH clearer on this issue!!!! We immediately unpaired our phones and so began the madness of finding something that IS compatible. We just got back from trying to find a compatible PDA style phone from T-Mobile who is our current service provider. NONE of their current offers work! I went to the wireless 4 BMW website and they list the Blackberry Pearl, the 8700 and the 8800 as compatible with the 2008 335xi. T-Mobile no longer carries the 8700 & 8800.The Pearl (the old one - not the new one with wifi) and the 8820 won't bring in the addresses - phone numbers only. BMW assist says that indicates an incompatible phone. Danger Will Robin DANGER!! We even went so far as to try a friend's iPhone and that did the same thing - it brought in phone numbers just fine but NO addresses for the Nav system!! grrrrrrrrrrrr I'm beginning to think that this whole hands free phone thing on the BMW is an overly fussy piece of crap. Should I take the car in for BMW to try to fix? Since both the Blackberry Pearl AND the Apple iPhone failed (both of which are SUPPOSED to work) I am now suspicious of the car itself. Quite frankly I am so annoyed by this that I am giving serious consideration to just pairing up our T-Mobile Dashes and calling it good. We love our Dashes! ARGH!! Are there any 2008 335 owners out there who are also T-Mobile subscribers that are having a better experience than this??? If so what phone are you using? Any and all assistance is greatly appreciated. Thanks folks!!
