I am looking for someone in the middle Tennessee area that has a navi tsx. I need to swap the navi box in the trunk to see if thats where my navigation problem is! Your navigation box will not be harmed in this deal. I am willing to pay you or buy lunch/brew. I am really desperate in trying to get my navigation back. I need to make sure that the box is my problem before I go dropping a few hundred bucks on a new(pre owned) one! Please help me out!

 

I'm not close to you to help you out, but if you find that the unit is indeed bad, you can get a replacement unit (refurbed) from Alpine for about $158 rather than the "dropping a couple of hundred" that you referred to in your post. The details are here in this thread:

Sweet man! I did a search but that never came up! That is the exact same problem mine is having! Thanks for finding that for me!
