I have both GB Discoverer 50k and Garmin Topo UK v2

the discoverer is .IMG
topo UK is hundreds of .img

the topo UK map will work in mapsource but i cant seem to get discoverer to open

I have installed the discoverer map to my device and it is working nice...

I think as i cant add discoverer to mapsource...
I will not be able to add any birdseye images to the map ??

so the map is as is and I can't change anything??


can someone also tell me the difference between topo and discoverer...
and if it is worth to spend time to make build the topo map in mapsource
to put on my device....

I want to use this device for weekend walks :D

ok so it has taken me all day to convert the topo map for use with basecamp on macintosh

but i do believe it was worth it !!!!

the discoverer map is basically just like the ordinance survey map and is great for out in the countryside or mountain walks

the toco map is far superior for use in urban environments....

now i need a bigger microSDHC card :D

so quick update.. I have been using the device today and I love it !!!!

for the conversion to macintosh I used crossover pro
to install the original topo map and convert to gmap for mac

the jetmouse keygen works nice in crossover also :D


the discovery map looks like someone has scanned the ordinance survey maps at best... or traced them with a felt tip pen...
I can't see how they can charge so much money for these maps... although as i said before I am sure they will be good for cross country trecking and mountain walks but absolutly useless for urban or city use !!!

I am so pleased i went to the trouble to convert the topo map...

now i can use the full power of the basecamp software to customize my map/POI/ add birseye imagary and loads of other cool features i didn't discover yet.... also I can plan my weekend walks just how I want :D

once the discovery map is installed on the device... it is also available in basecamp when connected via usb...
although I did not have time to see if i can add any POI or other extra features/content to this map yet...

I currently have a 4GB microSDHC class 4 expansion and it is working OK
I have just ordered a 16GB class 10 microSDHC from fleabay for £20
so I will have plenty of room for all the extras i plan to add on these maps...
