And the fight goes on

Did a MMI/Navi update yesterday (had P0022 on the mmi ), and that ofc. didn't go as planned either. First from P0022 to K0031 the "DVD device" update didn't go thru (took retry several times), and at last i had to skip that module. Then went to update from K0031 to K0257 the "MU9307 Device" pooped out. I sat down trying to retry that for well an hour since i don't know what the MU9307 actually is and was afraid it was a needed/high priority system. When i canceled that and all wrapped up i ended up with "MUConsistency -NOK" in the software update device summary.

I later found out that the iginition is supposed to be OFF, which i didn't know when i did the actuall update, i had a 50a supply charger on that i usually use when i update/troubleshoot cars though so the battery voltage never went bellow 12,3v. But apparently that's to low and might be why the updates failed(??)

After that i did a test start and quick function check of the car, and all seemed fine so i went forward with the Navi update and that went without a hitch. So did the MMI/Navi activation after that was done.

So when all that was done i drove the car home for the night (10.30pm at this point), and i tested the navi on my way home, and it worked ish. Route calculated and all that, gasstations and all those icons came up, but i couldn't see the road itself on the MMI, the voice guidance and dash guidance worked though.

So i drove it home and parked the car, without a charger to see what happened. And yeah, it was flat today as well -.-"

But ok, with all that said and done! Is it possible / how do it get to update the two devices that craped out on me? Feel like i have to sort that c**p out before i go any farther with the draining problem
