Garmin etrex vista Hcx which maps to buy?

[GrumpyGregry]

Been trying OCM and a Vista HCx for a few days as sat nav in the car prior to entrusting my self to it on the bike. The only flaw I've found so far using the routing in the OCM is the sometimes extraordinarily mistaken directions e.g. "take 5th exit from roundabout", at a rural T junction about 7 miles from nearest RAB. The map showed it correctly as a TR.

Thread necromancy - the GMAPSUPP.IMG file IS the map. Garmin use IMG to annoy and confuse.

The file needs to be in the SD card's "garmin" folder, for example: E:GarminGMAPSUPP.IMG
