That clears that up then. The garmin is the best and the worst , the 550 is better than the 660 , the 660 is better than the 550 , the tom tom is the best, the tom is the worst.
As a rider who has used all three(550, 660 and Tom tom Rider (Mk1 and Mk2) on bike, car and with the 550 and Rider, on a 7.5 tonne multi-drop truck,maybe this makes sense.
Easiest to use straight out of the box
- Probably the Tomtom
Straight forward A to B routing.
-Nothing in in for ease of dialing in the route and most of the time they all do the job OK. I have had problems with the Rider telling me to take one way streets the wrong way and turn right at no right turns. This was a real problem on the truck. The Garmins had no problems on the same routes.
Routes with waypoints
-Definitely the Garmins. Easy to add multiple waypoints and I used the feature to auto sort waypoints in best order to work out my delivery route on the truck.
Route Planning on computer
-Garmin wins easily. Although it is possible to use thrid party software to get routes into the Rider the dedicated Mapsource software supplied with Garmins makes it a no-brainer. I have seen complaints about Mapsource and Basecamp but I have used them with no problem for some years for driving and backpacking.
Map Coverage
For UK equal but go into Europe and the Rider shows a blank screen east of Germany and Austria. To go further means another map at extra cost. Garmins detail mapping stretches to Turkey and, for main roads, covers the world.
Outputs
Tomtom Bluetooth
Garmin Bluetooth plus hard wired for headset and mic or Autocom etc.
Customer Service
-Warranty Replacement on my Rider took eight weeks and only then after complaining to CEO of Tomtom. Garmin warranty replacement took three days. I have also had two Garmin's replaced for free after accident damage when out of warranty.
MP3
-Only on the Garmins
This is a straight Garmin - Tomtom comparison. Regarding 550 - 660. My preference is the 660 but the 550 took me all over Europe with no problem and my wife is still very happy with it.
Comparing Apples with Apples
Garmin comes with bike and car fittings, I think the Rider is still bike only with a car kit for about £50.00. The Rider has a Scala Rider headset and the Garmin requires either a Bluetooth headset or some sort of hard wired system at extra cost. Map coverage better with Garmin. So he it comes down to where you want to go and how you get the audio out. For UK and Western Europe and happy with the Scala headset maybe Rider is better. Want to use an Autocom, stray further from home and maybe use it in the car then maybe Garmin.
