I have installed the v26 more than a month ago and been using the system daily with no problems except the slow loading of maps when changing scale.

But since Sunday the system now jams totally and switching the engine off and back on again (straightaway) make no difference. You have to wait 5 mins at least till it starts again properly and also take the DVD out from the back. Also yesterday it seems to have gone to a very old very version (pic enclosed), and the navigation option disappears. Once again I took the NAV DVD (has no scratches and is clean) out and put it back in and then it works.

Very weird. May re-install v26 again unless the DVD Navigation unit is faulty?

Anyone else with this problem?
