Re: EVIC - can't find compass VAR (variance) setting
I shelved this problem for a few days. The EVIC was replaced with a S/H one sourced from a breaker in the US. The original one had a blown display. When I first installed it, it passed the self test using the procedure as in your post, however now the self-test can't be repeated.
A further annoyance has occured. Recently the horn started beeping when I lock the car - it didn't before - and there's no option in the EVIC to turn off the horn beep. I think there might be a bit of a mismatch between the BCM and this EVIC.
I am guessing that these settings are stored in the BCM, not the EVIC itself: when I first installed it, it came up in metric units, not US.
I might try disconnecting the battery and see if that resets things. Otherwise it looks like I'll have to put up with its eccentricities.
