Hello Brian. My GPS is having the same tracking problems. My settings check shows GPS receiver error. I looked in the trunk for a brass bracket to the left of my CD changer, but didn't see anything. I have a 2004 330Cic with MKIV and v29.1 upgrade. Is there some kind of panel to remove to find the trimble module? Any thoughts? All help appreciated. Thanks.
