ok... I have a 2007 328 xi with idrive and voice assist.... I don't have BMW assist and don't want it.... I just want to add Bluetooth... do I just need to install the $675 kit from bimmernav and have it coded?.... is this still tough to accomplish and is it most likely going to be in German?.... or do most dealerships have this down by now.... the tischer BMW is in Maryland right outside dc right?... I'm like 40 miles from there.... should I have them do everything?... or install the bimmernav equipment myself and just let them do the coding?.... after reading this post, I'm scared that this all may not be worth the hassle.... what should I expect to pay for the coding?
thanks for your help.
