I am new to navy systems so I dont know which brands there are and which ones are good or bad. I was looking at GARMIN, I was looking at the Streetpilot C320 and the Streetpilot i5. ANY GOOD?
Depends what you wanna spend but if you spend around 300 bucks you can find ok NAV units. When you spend more money you get nicer GUI, better POI database, etc.. Alpine is nice but the discs are the only thing you can use to upgrade the software. however at Canadiantire.ca yuo can find a Nexstar nav with a 7" LCD for about 450.00 and its not too bad.
