So Ive had my D2 for about 4 months now. Pretty much since I bought it, Ive had trouble with the nav's location.

The biggest problem is that sometimes (about 30% of the time) the arrow will go completely off into space. I think the problem has to do with a constant rotation that the unit does. For example, if I'm sitting at a stop light, the arrow will continue to rotate around and do a complete 360 over the course of a minute. So when I'm driving, it also rotates and causes the unit to become disoriented. Has anyone experienced this problem?

I have reset the calibration numerous times and have the VSS wire connected. The funny thing is that its more accurate right after I reset the calibration. I also have the antenna located on the windshield so thats not the issue.

Let me know if you have any helpful tips to fix this!

Thanks.

Does sound like a problem with satellite reception. When you go and look up your satellite reception how many signal bars do you see?

Do you have the metal piece under the antenna?

the reception is usually ok. The antenna was mounted on the windshield with the metal piece that was given.

Are you 100% sure the VSS wire is connected correctly? The VSS may be connected but is it the right wire?

Are you in a car with a curved dashboard, or does it sit straight? Reverse wire hooked up?

When you get to the display screen it will show antenae for reception. Let us know how many antenae you have shown...

The VSS wire is currently not hooked up, but when it was there was no difference. It recorded a speed pulse so Im pretty sure it was connected correctly.

I usually have at least 1 bar of reception with the full amount of satellites.

The Connection Status window says the reverse wire is hooked up.

The dash is slightly curved but that shouldn't matter. This is not a case of the arrow being a little off. The arrow will spin all the way around very slowly.

Thanks for your help!

1 bar is not enough for satellite reception. Go to your install manual and go over your placement of transponders...

connect the vss wire .

VSS is required
