My Nuvi 2699 worked really well for 12 months but now I get a message saying the supplied lead is not compatible with traffic. This seems to be across a few vehicles so its not a metallised windscreen issue. My unit has also told me twice this week that voice command is not available in British English. Software was updated about three weeks ago.
Any clues?
Mine's soooo annoying, the message pops up every few seconds no matter how many times you acknowledge it. I've turned off traffic in the GPS and still get the messages. Next will be throwing it out.
