My TDMA phone is labeled a 7790 phone, and Serge is almost right--no where else to get it. However, one dealer has quoted me 20% off list for a second phone (so my wife & I can switch cars as needed) to $476. Check the Roundel advertisers and ask around. (If you don't get Roundel magazine, sign up for the BMW Car Club of America, the largest in the world, & you'll get access to lots more info. My mebership # for referral is 90126) I hope to have more phone info from NA in a few weeks & will post it. Is there any place where I can get this phone for a cheaper price than through BMWusa.com or from dealer. If I go through dealer should I be able to get it for a discount?
