Garmin Gpsmap 182

[Midnorfolkboats]

Hello Technical People.....

I'm after some advice.  I have an old Garmin GPSmap 182 chart plotter, which has served me well over the years.

However, for no apparent reason its suddenly decided not to show the base map anymore.  When first powered on it says, "cannot unlock maps" and then shows "no map" on the map screen.

I don't have the PC interface cable to plug it into the computer to have a look and a master reset on the unit doesn't fix it.  If anyone has had this issue and solved it , I'd love to know how.

I have a data card for the unit too, which the GPS recognises and reads, but still says no map.  Any advice would be appreciated.  Garmin just said, "it's old, buy a new one"......

from googling it sounds as if the time zone map may have been corrupted, so that pc cable would be needed, though it may be tricky to find one.
