Good functionality but product life can be dire. My 735XT display failed just outside warranty. All other Garmin products I've had have developed faults within a surprisingly short space of time too. So, basically poor quality and potentially unreliable with a short life-span!! For what you pay you should get a lot more!!Poor warranty terms too, with basic customer support.UPDATESent me a boxed, complete refurbished replacement so this review goes from 2 to 4 stars.
