I am absolutely done with my TomTom Rider 400, it has ruined far too many days out.
Randomly stops giving voice instructions and speed camera alerts even though all the settings are correct. It'll tell me via audio when I'm due to arrive at my destination but that's it, I get no audio instructions along the way. Only fix I've found for this in the past is to bring it home and update it, which obviously cannot be done half way through a day trip. Having to look at the screen for directions is EXTREMELY dangerous while riding a motorcycle. I actually almost unplugged the unit and threw it in a field while riding earlier because it really is that frustrating.
Updates take 3hrs, yep 3hrs, no idea why and it's ridiculous. It'll tell you it's going to take 1hr but it actually takes 3hrs as the counter never seems to go down. Oh and once you start the update you CANNOT stop it, so you are then stuck with it locking up your internet connection for 3hrs. If the update is so slow how on Earth does it completely lock up an internet connection? The data trickles in so slowly yet it somehow uses all of my 100MB connection rendering any other devices useless for 3hrs!
Imported tracks and routes are a complete joke, literally impossible to join a route or track part way through, the damn thing constantly tries to make me go back to the start point, usually through farm tracks which is not ideal for a bunch of tarmac munching cleaned and polished streetfigher bikes.
Using the unit is extremely sluggish, navigating through the menus is so slow, there is literally a 1 second delay after pressing any of the buttons.
Avoid Motorways just does not work, often puts me on a Motorway.
Awful route planning software
I've had it from new and I've persevered with it but it's ruined it's last day out now because I simply cannot rely on this thing to lead a pack of riders anywhere reliably. I honestly cannot think of anything that is good about it so I'm switching to a Garmin, I'm sure Gamrin's have their faults but given every single aspect of this TomTom Rider 400 delivers an awful experience I find it hard to imagine that a Garmin could be worse.
