Z2 - everything seems to work except the speed indicator. The status remains on initializing constantly (3000 miles plus) , left and right turns are registering, but mileage logged on the speed sensor remains at zero.

Not sure how long it should take and patience... I've reset the calibration. After 2 weeks and over 500 miles, the Speed reeding was still at 0, the turns were each around 50%, and overall was 1 bar (5%?). Since reseting, speed is still at 0, turns are at 25%. Speed pulse changes, but reads 6 digits always (ie, 538582).

I have the same issue after dealer installed Mod. Can not access speeedometer, and a few other functions. I'm not 100% certain my installer did the re-boot, and am wondering of I should try this. I don't want to make the system worse by resetting, as I am thrilled with the current functionality - I just want more more more! I had the Sirius Sat installed, and I'm thinking of adding the XM as well - can you do both?
