I purchased the Oregon 300 a few weeks ago from REI, the touch screen is awesome, but we are having trouble downloading caches from our MAC. Until this is solved the GPS doesn't do me much good as this is the main reason I purchased it.
If using for driving, the maps aren't very detailed for the roads. Only main roads show up - and it says something the to effect that maps aren't supported when asking to make a route. We will need to by the map upgrade I suppose. Also, I haven't figured out how to put in street numbers.
In addition, I haven't figured out a way to manually enter coordinates - this may occur once I can download successfully. I don't know.
Keep in mind I am new to this unit, so there is a bit of a learning curve.
