look man why not just stay off and let someone else chime in. You just killed the thread. If it was so easy, I wouldn't have posted the question. That said I still can't find anything. If you're one of those Bemmer snobs, back off. If you have an answer let's have it. I have memberships on other high tech forums, I build high performance cars, but I can't find any info on adding a nav set up to this car my daughter has that doesn't come with nav. Now if you can help, help if not bug off. if you really want to know something about high performance come post on NA-T or Supraforum or stangnet or just keep toot tooting your Dad's nice Bemmer horn.
