Sorry for yet another query, I have read multiple threads but I'm still looking for advice as most threads seem oriented to longer distance DS touring, multi-day rides, etc. I don't have a GPS, haven't used a GPS (other than a borrowed Nuvi in the car once) & want to have something to track trail rides/explore others GPS tracks, off-road. I don't plan to wire it to the bike (250 w/minimal electrics) at this point, so the power connector issue is not really a main concern & in the end don't really mind changing batteries, since I ride mostly day rides. Montana is too much $$ & sounds like more than I need, so I've narrowed down (not knowing much) to either a Garmin 78 or an Oregon 450. Suggestions/insights?
