US MMI update candidates, please be careful: if your version is between 6.00 and 27.50, two steps:

[pierreb]

First with Update CD 4F0 906 961AB and afterwards with Update CD 4L0 906 961 H. DO NOT ATTEMPT to go from anything less than 27.50 to 41.40 directly. DO NOT ATTEMPT if your nav disc is less than V5. TAKE OUT ALL CDs and IPODs (if you have AMI, no advice to Dension GW500 owners yet...) YOU MAY NEED TO RUN THE UPDATE MORE THAN ONCE until all the devices are done. repairs are over $2k if you need MMI replacements...you've been warned.
