I have a Garmin 178c that I use with a preprogrammed data card (Pacific) in Salt Water and a 32mb data card that I load from a my Mapsource CD's for in the Columbia River. I was given a US Inland Lakes MapSource MicroSD. Is there anyway I can load or copy the data on the MicroSD to the Data Card or even use the MicroSD card at all to load into my 178c? My PC can't read it at all. From what I can tell.. I am stuck with a useless MicroSD card... or get rid of it to someone who can use it.
