Hi, I have recently acquired and retro fitted an RNS-E to my B5 A4 and am very pleased with it.... Except... When in Nav Mode, I can chose a destination, the route is planned and shows up on the map including different route options, distances ETA's etc and I can read the route bit by bit page by page... BUT... When it tells me to 'proceed to route to start navigation' or something similar, (to start the navigational assistance) I then get a message similar to 'Route guidance cannot be started as you are not on a digitised road' Even though I have been on the M20, A259, A260 and other main roads in Kent. The map shows the arrow at the location of where I am and follows the road system albeit with a little delay on occasion but shows me to be on the main roads I am actually on. (Put the lazy location updating down to the **** weather and storms preventing a 100% signal) Anyone know what it means when the 'Not on a digitised road" message comes up, especially when I am on a Motorway which has been here for the last 25 years or more. I have tried the original disc; genuine Audi 2008? ish edition and an Ebay special 2013 copy and get the same error messages spoken to me through the unit. Any ideas would be greatly appreciated.
