I think you should buy the Nuvi 200, as its more portable and stylish than the bulkier c340. If you can stretch your budget a little there is now a Nuvi 200W and there are some good prices on Ebay. Garmin are excellent GPS units; so at the end of the day you'll be fine with either one.
I'm buying my first GPS. Don't even know about its features. I did some research. But since my budget was around $175, I was able to narrow down between 2 options based on COST and most positive REVIEWS on all websites.
1. Garmin Nuvi 200
2. Garmin StreetPilot c340
NOW, I DON'T KNOW what to choose. For what reason I should pick up either of those ?? HELP me with this PLEASE......
