Sat nav problem

annieoburns

I rarely use my Garmin nuvi but now it seems stuck with
"no detailed maps found that support routing. The nuvi cannot be used without them" on screen. The only thing it responds to then is the off button.

Anyone advise what is up? Do I need to get upto date maps or is the time up on ones I used to have? about two years now.

The maps on the GPS device have been disabled

Looks like your code is corrupt, follow those instructions and it should sort you out.

Have a look around the GPS forum too, if the above instructions doesn't work.

Thanks for the quick response in my hour of need but I do not think I will have time to tweak through at the moment. At least I have a cable from an old phone to connect to computer, I dont think I got one with original satnav. I found it handy to recharge the battery to have ready for a 'run'.

So there is hope! I will get back to it THANKS all
