KabulATC Posted March 17, 2009 Share Posted March 17, 2009 After having some problems with our Nav system (2005 RX330), it was getting lost, would work fine for a little while then all of the sudden not have a clue where we were, anywhere from several miles to several states off, we took the car in to our Dealer. After a day of research, it was determined the recently installed XM radio antenna was causing interference, and when moved, the Navigation signal strength returned to normal. We have yet to test it, however my wife will be taking a trip later this afternoon and we should find out if the fix worked. Just thought I would post since I have seen alot of posts regarding the system getting lost, and this is a possible solution for that.
