I have a 2008 C300 purchased "used" which is equipped with a Garmin GVN 53 GPS (must be aftermarket since activation button is mounted on the console). Recently the GPS stopped working. It turns on but stops short of allowing me to enter a destination. Garmin suggested that I update the SD memory card. I was able to purchase a card and download the update. My instructions were to insert the card in the control module and it would automatically update.

PROBLEM: I cannot find the module. Can anyone tell me where the module box would be mounted?

Thanks,
