Nav screen issue

[ahjones13]

I have a 2014 Journey Limited. I had to have the unit replaced about a year ago. I already had sirius/xm radio account before I got my journey, apparently when I trial membership on the vehicle expired the whole touch screen unit stopped working. Today, the touch screen was on the radio screen and flipped over the nav screen and it's just a black screen. The radio, phone, climate, etc, all work fine. The only screen that is black is the navigation screen. Any ideas?

you can try unhooking the negative post on the battery for a bit then trying it again

So I was finally able to go out and disconnect my battery. That didn't help. Is it possible the nav unit itself is unplugged. The icon for the Nav station had a SW on it, now it just has 2 dashes since I disconnected my battery.

The heading info comes from the on board compass - it will come back after you recalibrate the compass - details are in the owner's manual.

Thanks for the info. That's good to know, I just assumed it was picked up by Satellite. I am also wondering if I didn't leave my battery disconnected long enough. I left it disconnected for about 45 minutes, I expected to have to reset all my preset stations and reconnect my phone but everything was still saved. Makes me think I didn't disconnect it long enough.
