@Ishai-Ratz
Can you elaborate a bit why your preference is to use tracks as opposed to route ?
Hi @Ishai-Ratz I'm sorry to hear that you are still having problems with the .itn route. I have no idea why this is happening!
I used to have a v2 TT Rider that only used .itn and then I switched to a Rider 500. I missed seeing the route points on screen but soon got over that.
An .itn route is just a list of places in the order you want to visit them. The TT Rider software will calculate a route between all these points according to your settings, like fastest or shortest route. It will also use various map data (See TomTom IQ routes), traffic data etc.
A .gpx track is like a record of a route ridden in the past. It describes a route meter by meter without deviation. Nothing is recalculated by the TT Rider.
I plan my routes (.gpx tracks) meticulously (almost metre by metre) and I do not want to be taken away from my intended route because Mr TT knows better! 
I also like the ability to be able to upload a new route via my phone and MRA account without the need to plug in.
A lot of people still like the .itn format and that's fine, but my personal preference is .gpx (perhaps I'm a control freak!
).
