I have an 03, I did this mod and I don't have any trouble with the compass, but after removing the relay I have a flashing light on my dash, the icon is a car with a key over it, It makes me think its a "Your key is still in the ignition" light..
Anyways, everything works, doors lick, anti-theft, etc.. just this icon flashing on my dash now.
Anyone know exactly what that light is and if I can disable it and keep the always-on 12v outlets?
Edit: I should have mentioned that the light goes off when the truck is running, so its really not a big deal, just sort of one of those "non-pefect" annoyances.
