I have a D2 unit that works great except that I can't not plot a destination, and all but POI and one other icon are greyed out.

The info screen shows parking brake off, and good GPS signal. All other information shows working and active.

The map works, and the GPS is accurate and follows correctly, just can't set home or a destination.

Can't figure out what the issue is, but it would be of great interest to me if someone could help me make my nav unit actually navigate!

You probably want it to show parking on, did you do a bypass? When the parking break is on, it grounds and it will let you access the screen. Otherwise you must do the bypass to use it will traveling.

You either need to have the parking brake on or bypass the unit if you want to be able to use the greyed out functions.

did i hear an echo? lol just messing!

The obvious bites me again. I guess parking brake "OFF" was the key there. It was supposed to be bypassed when I bought it, guess that isn't the case. Thanks a lot for your help.
