im having troube with my navigation

the red arrow is always behind the point where my car actually is... and if i go slow enough, it doesnt register at all and then im far behind..... any ideas?

i dont know wat to do... im real disappointed thus far and its caused me to miss turns... i tried playing with that "modify current location" button but it seems to reoccur...

How is your satellite signal strength, and is your VSS wire hooked up?

signal strength is ok

and i had it professionally installed, so VSS wire should be hooked up...

I wouldn't count on that. There's been a few people who had them professionally installed and it turned out they never hooked up the VSS and/or reverse signal wires. To check if the VSS is hooked up, go to:

SETTINGS > HARDWARE INFO > CONNECTION STATUS

Look at the SPEED PULSE reading. It should read zero when the car is stationary, but the number should go up as your car's speed increases. If it remains at zero while your car is moving, it is not connected or connected improperly.

Also, go to:

SETTINGS > HARDWARE INFO > CONNECTION STATUS

And see what it says under the LEARNING STATUS category. It should say "3D Hybrid"... if it says "Simple Hybrid" or "Sensor Initializing" something isn't right.

i checked out the situation there.... it says 3d hybrid

and it takes the car to be going about 7-8mph before it starts to register on the speed pulse and it went to about 6-7 at around 30mph
