I'd be tempted to cut the back out of my globebox liner
You can get an RNS-E for that price and use the SD card slots instead.
Why not put the R2500 (plus the cost of the harness) towards an RNSe? Then you will have two built in SD card readers and navigation?
Cheers John! My glove compartment looks exactly like Staz's.
At the risk of sounding totally stupid, would you mind pointing out what part numbers will be required from the ETKA pic you have posted? From what I can see I will require Item 13 and 14 and possibly the entire glove compartment as you have pointed out already. **** this seems like a very costly exercise
