I can re calibrate my GPS 50 x's and it still gets lost. I have found that it does not show GPS in the left corner while driving down road. This is right under the compass. Also when accessed service menu NAVI has code 58-40..... Can any one help get my NAVI working right again!!!!!

Your unit does not appear to be receiving a GPS signal. I don't know what the code represents. You most likely need to call your dealer.

I park in an underground garage at work and while underground I do not see "GPS" in the left corner either. This is what leads me to believe that your unit is not receiving a GPS signal. Maybe there is an antenna somewhere that has come loose.

There was a TSIB for this problem that would upgrade the DVD disc to the next year. I'm not sure if the GX 470 was covered. You may want the search and/or post in the first gen section for the GX.

Correct does not show it is receiving GPS signal, have the most recent DVD out. The antenna is located in the glass rear side windows, not sure how to test them. Hope someone had this same problem and knows a easy fix, dealer fix will be an ungodly amount I'm sure!
