compass

i recently installed an overhead console in my 1998 blazer. I have tryed calibrating the compass many times, but nothing works. The screen shows 0 C cal NE. I have set the variance correctly. And i tryed holding in ON/OFF and US/MET buttons for 10 seconds. It continues to show 0 C cal NE. I drive in 3- 360 circles around 5 mph. Nothing happens after that.

any help would be great
Thanks

I assume you have properly tapped it to the VSS circuit, that said, hold both buttons at the same time til it says CAL, ignore anything else till it says that, it may be more than 10 seconds.. Then drive to your right in a very tight circle (full lock is best). I had to go 7 times till mine caught.

If yours still refuses to do that, I would suspect you're not tied into the VSS properly.

i thought i had properly tapped into the VSS wire, but i checked today and the connector wasn't properly installed. i installed it correctly and calibrated it. now the compass works great.
thanks rlith

OC means open circuit, your temp sensor isn't connected correctly, or the temp sensor has a bad ground.

Your vss connection may not be good as well.

Doh! Didn't even think to ask if he had the temp sensor installed! Good call..

hahaha, we've both spent so much time monkeying with these things, it should've been first on your mind!

when i said, "0 C" i meant zero degrees celcius.
sorry

when i said, "0 C" i actually meant zero degrees celcius.
sorry

Are you sure? Does it show a farhenheit temperature?

yep it works with celcius and farenheit. i have checked several times to see if it is accurate.
