For those who like to be informed, one of the differences moving from F/W 2760 to F/W 3810 is the fact on F/W 2760 you could enter postcodes on the go, while the car was moving which was great for the job I'm in. But on the F/W 3810 you can't enter the postcode on the move anymore (It's a safety feature)
So basically F/W 2760 you can enter postcodes on the move
F/W 3810 you Can't enter postcodes on the move
