RSN-E problems, dirty lens ?
Hi my unit has started to sometimes take an age to come on displaying "sat nav Initialising" before eventually working. If you try reinserting the disc it gives a disc unreadable warning.
The disc I am using is genuine audi so I think the problem could be a dirty lens or even the heat as it is worse on hot days.
I am happy to remove the unit but can someone tell me how easy the lens is to clean with regards access etc.and how to do it.
I thought my first option would be to clean the unit with compressed air and use alcohol swab on the lens.
