For all mmi 3g nav + long term tmc crashing and now turn left navigation voice prompts issue there is now a repair software update so contact your dealer

the update disc revision T

Incorrect voice commands on roundabouts while mapping on the MMI 3G screen and instrument cluster rectified

Loss of FM radio reception without automatic retuning and TMC on a long journey if TP is on

Also there is a similar update for mmi 3g cd rom based navigation revision disc AA

The update discs bring the MMI 3G navigation guidance on earlier vehicle models up to the same standard of MMI 3G as that on MY11 cars, and is similar to MMI 3G+ guidance. Preliminary tests in the UK suggest the new software is a satisfactory improvement over the previous software.
