The amplifier for the M Individual Audio System overheats and turns off. The affected amplifiers are not equipped with a cooling fan. (Vehicles produced up to March 2008)
Install an improved amplifier (including a cooling fan) for the M Individual Audio System.

Hmmm. Mine is a June 008 production and I have had my amp shut off on me once. I was listening at hihg volume for about 5 mintnues, and it shut off. Turned back on after about 10 minutes. The dealership looked at it but could find no issues. I typically do not listen to it loud...hardly listen to music at all for that matter, so it is not a huge deal. But, if there is a "new and improved" amp for it, I should get it...if only for resale down the road.
