"Nice unit with some faults"3.5 starson by grtgrfx
Pros: Large bright display, can read with sunglasses on, great multi-lane steering feature, custom maps
Cons: So-so battery life, lower-than-expected speaker volume, awful FM transmission, still complex menu operation
Summary: The Go 720, especially at the refurb price of under $170, is a great unit with a few problems. Compared to its predecessor, the TomTom Go 710, this new model is slimmer, wider and has a much brighter screen, so much so that details are easily visible even with polarized sunglasses on. New text-to-speech makes navigating easier by speaking street names, and the user-customized maps keeps your Go 720 more up-to-date without spending over $100 for TomTom's maps.
Bluetooth connectivity is unchanged, but FM transmission to route audio to your car's stereo system is a new addition. Unfortunately, the transmitter is pretty weak, not even extending from the front of your car to an antenna on the rear fender. All I got was static when I tried broadcasting music to an empty space on my radio, even when I held the GPS above the rear seats, so it was useless to broadcast directions through the radio.
Charging through the supplied cradle was relatively quick; not so from the included car charger. And note...if your car, like mine, turns off power to your lighter jack, no charging will take place with the engine off. That's a negative if you aren't planning to drive for two hours and not use the unit, since it appears not to recharge much, if at all, while in use. My unit got only a few hours of use before requiring a recharge; the prior model had a longer battery life. Of course, if you don't mind a cord running to the charger, it works fine while plugged in.
Cranked all the way up, some voices were just not loud enough while driving, and a few others overloaded the sound output enough to distort the speaker and cause the display to flicker in alarm -- the first time I'd ever seen a GPS overloaded by its own audio.
Navigation is generally good, a common feature of TomTom units. Signal acquisition takes from 20 seconds to three minutes or so. While maps are generally accurate, the system sometimes avoids viable side-street shortcuts, and is biased toward using major roads for navigation. On the other hand, it sometimes takes laborous pains to reacquire a route if you stray by a few blocks; you can take quite a detour into residential neighborhoods trying to backtrack where a simple U-turn would be more efficient.
In summing up, if you follow the Go 720 fairly closely, you will get good directions to get to your destinations. It's easy to read, accurate and darned useful. If TomTom fixed the FM and volume issues and made the battery last longer it would be a truly great GPS unit.
