Thank you Neil, Garmin-Nuvi and everyone else that has helped me.

I have been making short trips each day and it "seems" to be navigating as it used to. I am going on holiday in a couple of days so hope that its working correctly for that.

If I need to I will come back here as everyone has been very helpful.

Can I mark this post as "solved" or do I just leave it?

Kind Regards,
Keith
