It'll be nail biting time when I connect as I've been promised everying is ok on that front as I have Lifetime and a Nuvi ??? for the car - basically top range last year.
It updated last week when I connected it but when last week's purchased Zumo 660 was connected it said no updates available, latest version installed but as of Friday my car one was ahead of the Zumo which I thought a bit odd.
Oh well - nothing ventured and all that...
