Please say how you were updating the map to the unit, was it with MapSource [which would load the map as gmapsupp.img] or was it with MapUpdater [which would load it as gmapprom.img].

Can the unit be seen by [Only registered and activated users can see links. ] and/or [Only registered and activated users can see links. ]? Check you have latest [Only registered and activated users can see links. ] loaded before checking if it's seen.

Thanks Neil. Re-installed drivers. Was updating with MapUpdater. Unit is not seen by any software, none ,ZIP :-( Checked with my other 2720 and all software see it
