Absolute newb question here. Im very new to GPS so trying to work it all out.
Ive recently purchased a Garmin Colorado and am trying to load a number of maps onto it. Although its got plenty of memory (4GB SD HC card)
I dont seem to be able to load all the maps I have :-
Topo Plus (Johnny Appleseed topographic map - I realised afterwards I could have used shonky maps instead?)
Including the bundled base map I seem to be only able to install 3 maps.
When I download a 4th map it just overwrites an existing map with no warning.
Is there a 3 map limit on the Colorado? Just wondering what Im missing here.
Ive done alot of searching and I cant find much info in the manuals or on the web about this.
Also, is it possible to view all of the above 3 maps simultaneously on a Colorado?
Thx in advance for any help you can give me.
