N1 GPS Arrow problem

[SolidForce]

I have a N1 with a N3 brain, rear camera, ipod, and xm.

 

This all started when I updated the firmware after doing the bypass for new maps (had the 2006 maps, bypassed and updated to 2008 and now updated to 2009). Everything on the unit works fine but the arrow that represents the car in the NAV points the wrong direction. If I go into settings and "modify current location" and set the arrow right, it works for a while but eventually points the wrong way again. Very odd. Sometimes it goes so bad as to actually turn itself completely around...say I was going North, it would point the arrow South and show me traveling backwards.

 

I have checked all connections multiple times, reset the brain to face the front of the car exactly (even used a level to make sure it was as perfect as possible). I can't figure out why the damn arrow will not stay pointed that the way my car is pointed.

 

Some things I am thinking:

 

1. Could it be the media that I made a "backup" of the nav DVD on (slow to read)? It does whirr a lot.

2. Would the bypass affect this in any way?

 

Thanks!

Solidforce,

I actually occassionally experience the same problem after downloading and burning a 2009 copy of the East disc. I do not know if it is a fault of the burned disc or if I should connect the reverse wire from the wiring harness to the back up light on the vehicle. For me this is an intermittant problem which leads me to believe it is a disc problem but I do not know for sure.

Does anybody have any insight to this? In addition does anybody know if there is a connection under the dash for the reverse wire from the unit to connect to? I have an 1999 Gmc Suburban.

As always thanks for any help.
