Garmin StreetPilot c340
The Garmin StreetPilot c340 is in the middle of the “c” series. The big advantage it has over the c330 is text to speech. This means that instead of the voice prompts saying things like “turn left in 100 meters” it will say “turn left on Main Steet”. This can really be an asset when driving city streets and you don’t want to look over at the GPS screen to confirm which turn to take.
Additionally, the c340 can be upgraded with an optional FM TMC traffic receiver. This means that live traffic information can be sent to your StreetPilot to alert you of accidents, construction, or simply rush hour traffic. When applicable the c340 could then route you around that traffic if a faster route can be established.
If you want to save a little bit of cash, you can opt for the c330 if you don’t mind not having text-to-speech nor want the optional traffic receiver. Otherwise, this is a good pick for the feature mix and price point.
