need help with rino 530 hcx

[68ss]

Hi everyone, I have  rino 530Hcx and want to put a TOPO map of the san juan national forest in SW colo on it. Im not sure if im doing it correct but ive downloaded several maps on mapsource and they all seem to come up short of what i want.They show different sections of colo or no elev just roads. I'm looking for a map pretty much like the picture advertised in cabelas magazine of the unit for sale.  Any advice would be greatly appreciated.
