I have a new to me 2002 CLK 320 convertible. It came with pretty new navi cd's from 2005 (navteq). I put in the CD for my region (southwest) and it showed my car was in the pacific ocean. I set my location manually via an intersection and set my destination and headed out. Worked great for about 10 miles then went all wacky. It had me doing a U turn on the highway etc. Seemed like it lost it's mind!

I cancelled that route and on the main map screen noticed it said 00 SAT which I believe means that it is not getting any satellite reception. What do you think could be wrong? Is it that antenna or???? Where is that antenna and how can I check this thing out? Strange that it would work for 10 miles perfectly and then never again! HELP!
