Thanks. I sort of figured it would just be easier to buy the official maps, but i'm on a budget otherwise i would have. I couldn't find a HC unit for a reasonable price so i went to eBay. and even after a bidding war it was less then retail, until the C.O.D. hit my door. heh. oh well.
I managed to get icybus to work on my unit/mapsource. it was just a real pain in the but. i managed to fluke out and accidentally find a youtube video that explained it and various other things. very informational.
I loaded up Vancouver and the lower mainland plus Victoria, Nanaimo, and most of northern Vancouver island. That was on the highest detail (i don't know if that detail option in mapsource effects what gets transfered to the map, if not, disregard) It seems like enough for me for now. i can switch out maps if needed. i was worried without an SD slot i would be short of memory but this seems like enough for my uses. If the higher quality maps allow me to fit more on there at a better quality or with more updated map data it may be an idea for me to upgrade in the future, But for now i have to stick with the free stuff.
Thanks for the info. it helps.
