Just looking for GPS recommendations. I have always used my phone, but thinking I might get a dedicated GPS. I have been thinking of getting a decent car GPS and a rain proof cover for it. I've read mixed reviews on some "Motorcycle" GPS units. There are some nice features of a motorcycle GPS like being able to select curvy roads etc.. However these come at a premium and not sure the added expense is really worth it. One thing I do like on my phone is being able to select "avoid highways" for more scenic roads. Just looking for opinions. Thanks
