NAV/GSP issue
My 05 E55 is having an issue with the GPS. When I drive it sees me moving...but the map is way off. I searched regarding this issue and found others with this problem...but they were old posts with no resolution. Any thoughts?? Its almost like my GSP issn t getting a strong enough signal. Oddly enough...this started right after I got the car back from my EVOsport header install. Perhaps something went array due to disconnecting the battery? Thoughts?
I have heard of others having this issue...but no one has ever posted the root cause or what can fix the issue.
Possibly the antenna coming disconnected?
