I have a TT XL.

1. According to the model comparison chart, this seems to be similar to the XL340. That one uses a newer boot loader and a later Navcore.

2. Can/should I upgrade to the later Navcore?
Would I get things like IQ routes?
3. Or should I be happy with what I have now, which is the latest 870-map running fine?

Thanks a lot
