Summary: I have owned the previous version of the TomTom Rider and was less than thrilled with the long term support, thus the only 4-star rating at this time. With the old unit, the mount was a weak point. After about a year or so, the mount would fail to charge the unit and replacement mounts were not available in the US, only through the TomTom UK store at roughly $100. For a $400 unit, that is a substantial percentage of the total cost.
Summary: Needed to replace a Zumo 550 that had failed. After looking at prices and options made the decision to buy the TomTom. Overall it has most of the features that I needed but with the price difference between it and a new Garmin made the decision to buy the TomTom. Screen quality is good and unit easy to operate. For the difference in cost I am pleased with the unit.
Summary: Nice unit works great with gloves but the software takes some getting used to. Also the GPS menus are different than what I am used to. If you already have a TomTom I am sure you will have no problems. Linked easily to my Sena headset in my helmet.
Summary: The winding roads feature is awesome. The unit is user friendly and works well with gloves on. Still learning how to use all the special features. The Tyre software I'm finding it hard to use or understand, a how too tutorial would help a lot. I still think overall the unit is a great unit from a quality built point of view.
Excerpt: Nice durable unit. The winding road button is wonderful for wasteing time on a spring day. The included software could be better, but it is free. Operating system is standard TomTom. Drawbacks are that there is no audio jack. If you want to hear instructions, you have to use a bluetooth headset. Also your ohone has to be paired to the GPS, then your headset paired to the GPS to use the built in phone features.
Summary: I have used two different Garmin GPS units extensively (first a Quest II and then a Nuvi 550) on long distance motorcycle trips. The Quest was slow and the screen on the 550 was poor in sunlight but overall they were decent units. The Killer for me was Garmin's miserable map update system and terrible interface software. So I purchased the Tomtom and have been favorably impressed.
