I have a version 2.4 of system. Once bluetooth connects for some reason PCM restarts every 10 minuts. The only change that happened was, I have activated XMSirius. What to do?
Thank you

 

You need to have a dealer re-flash it. That usually solves the issue.

 

Your PCM software is too old. Ask your dealer to upgrade it to v2.47.

 

Any way I can update it myself?

 

Yes, but you need a $3000+ PIWIS 2 computer to flash the PCM. Dealer upgrades PCM for free if under warranty. Otherwise $80-100 is expected to pay for it.

 

No, go to the dealer. It still under warranty.

 

No wty left.

 

Had the same issue - apparently it was a bug caused by an XM update last year (no idea why). Went to dealer for reflash, fixed all the resetting issues once and for all. Cost me less than $100 btw - without regard to any warranty. I am at 56k miles, and am the 3rd owner of the car - and although I actually have an extended warranty that the last dealer sold me (with a deductible), I paid out of pocket bc it was so cheap.
