I've noticed that every time I use Navigation mode on my retrofit RNS-E, the DIS is left in digital speed display mode (even after ignition off & restart). To go back to the normal DIS display I have to press the DIS "reset" button twice. As far as know it is all VAGCOMed OK, and this it the only strange behaviour I have noticed. Is this normal behaviour? If not, is/are there some setting(s) that need changing either in the RNS-E itself or to something else via VAGCOM?
