At the moment I have the base map and UK however I want to add Barbados so I have the following on one storage card

• BARBADOS
• BASE MAP
• UK

The UK MAP is currenty called GMAPSUPP

The BASE MAP is called GMAPBAP

The BARBADOS MAP is called gmapsupp (however I cannot add it is called the same as the UK MAP) is there anything I can change it to so that the device recognises all 3 maps on the storage card?

you can add only one map file to SD-Card GMAPSUPP.IMG
what is you device ??

if you use internal memory rename UK map to GMAPPROM.IMG

IF you want add two map to same GMAPSUPP.IMG then you must use Gmaptool and Join them

Thanks for your prompt reply there I appreciate it, where abouts do I put the map on the internal drive? I am using garmin xt mobile on a navman pin I have 2 maps on the SD card already.
