[daviesbike]

have checked all fuses they all look ok ?

have also wiggled the connections in the boot on the tv tuner ect and still nothing ? its driving me nuts

it came on again as if it was going to load up and the radio came on and it said updating radio menus and then it just died again and back to square one and its still dead as a door nail ? what the hels that all about

its winding me up now because the car is simply useless with out the MMI unit working there in no control over anything !
