Review title: It's good but sometimes wrong
Product review: The Garmin C340 Portable GPS is an amazing little device. It is easy to install and easy to use. It is probably accurate 98% of the time but it has a few glitches in it as far as naming roads. I would have a map handy just in case. If you leave it on all the time the voice can get somewhat annoying. We are going on a long trip in September and I will re-review this device after we get back.
