A few weeks ago my nav stopped working. When I go to the system settings it shows no antenna. I tried a new antenna and it won't pick up satellites. I plugged the old one back in thinking I would order a pioneer antenna to see if it would fix it. Haven't done that yet but last weekend it started working for a little bit but when i shut the truck off and restarted it it stopped working again. I'm thinking its a software problem. Does anyone have a good link for updated files? Or any suggestions on a possible fix?

have you hacked your firmeare.  I wonder if reinstalling your firmware would fix it?  my nav also stopped working.  I am unsure what to do.  any ideas?

i've pmed you the link to the files i found that fixed my boot loop issue. try the back up files?
