Addendum: Oops, TomTom has written to me and I also have a link ([...]) for a German manual. Now I will first of all study the manual and a software update has been promised. So, maybe there is something else indeed with the Rider 400. Anyway, I increase ever on 3 stars because the customer apparently still what counts.
Nachtrag2: In the meantime, the German manual is quite normal for download. The manual worker understands this Navi much better. At least I now understood how I look POI and what options I have with it. The speed cameras now work permanently. After mounting another mount on the handlebars, I unfortunately had to find that the holder by the possibility of turning 90 degrees still remains unstable. On good surface it is ok but even the smallest irregularities lead to tremors and shaking the display is barely legible. This should / must be reworked because otherwise only a matter of time until this breaks sometime necessarily. The weak point is the rotating ring because this has some play. Maybe a damping could provide with a rubber ring for Remedy and the riders will still rotate. A fraction of the support I had in the old holders already and thanks to the assistance of a workshop in Sicily I could ever go on with Navi. By altering the mounting, 1 inch ball directly on the handlebar, I could now mount the Navi closer to the eye. Now the display indicate desirable nevertheless the numbers and keys would be set to make a little larger so that they are easy to read and keep your eyes on the road. Total remains as a conclusion: I'll keep it and hope for a vernüftiges update. Since I bought at Amazon, I'm in good hands with a possible fracture of the holder and take the risk. At the moment I would go to 4 points if the changes are actually implemented.
Addendum 3
Holiday weekend Luxembourg was announced. Unfortunately, the return time 2 days is over or I would give it back immediately. The reason is due to the lack of routing the read us go once just 100 Km although the route was previously stored on SD card. There is probably a service error and perhaps any tricks are called but I'm going for 20 years and had Motorradnavi with no such a fuss! Next point, sometimes quickly searched for a restaurant nearby. Entered the restaurant and what a joy in 3.8 km there is something to drink and eat. What a flop, the thing takes me 1.5 km away from the restaurant, no turning, no mention wrong route and after traveling 7.8 kilometers just someone with the Garmin leading the way and we found the restaurant immediately !!!! Hello what a ..... I write here but not the laughter of the other 4 people sat. Perhaps the current route must first be deleted ??? but what's the point, I am the customer test ??? At 1100 km, the behavior in the roundabout and so could be tested. Sometimes too slow and then just with a lap of honor at the roundabout, the ads on the page should show the reverse. The current status should top and not the bottom so it can be recognized more quickly because they are much too small anyway. Toll would be if the speed camera detector would einstellbat (eg howling, siren or so), if not soon a reasonable update comes I'll sell that thing, and then there is definitely no more Tom Tom. Meanwhile annoys me the Rider more than I have joy in him. Am certainly not the perfect Feak but simple operation and reliable route guidance are absolutely mandatory and it is not currently saved when Rider 400. Just as I'm doing up to other users and the customer should finally be taken seriously. With so many problems that it is easy insolence of Tom Tom. Downgrade to generous 2 points.
Phoned Eben Amazon and what a great service.
Although the 4 weeks exceeded by 3 days, I now get another Rider 400 and if it is working correctly I can not return anything. SOOOO excited to customers - many thanks !!!!!!!!!!!!!!!!
