Just bought 'New' nüvi 2350

Ive just bought what the ebay seller says was a new Nuvi 2350.

i pluged it into the pc and went to the garmin site 'my dashboard' , it says item is already registered ?!

i expected to be able to update maps with the numaps 60 day guarantee, but as its been used before , im stuck with an old map.

So i went into the garmin directory with satnav plugged into pc, and i cant see the map file anywhere.

i have a garmin nuvi 710 and had no problems with the maps on that unit.

So i want to update the map and also the junction view or lane assist.

how can i do this ?

thanks

I'll answer my own question.

map files are if a hidden system folder
