Hello @tosh1,
You need to know some informations :
1) what device do you have : Nav2, Nav3, Nav4 ? "high-level-u" map is for Nav2, "nav3" for Nav3 and Nav2.
Nav3 maps can also be used in Nav2 devices. Optimized for Nav2 if you're short of memory.
2) what size is your inner memory ? 1Gb, 2Gb, 4Gb ? Can you add a SD Card ? 1 to 16 Gb, max 32 Gb.
3) what coverage do you need ? what countries ? Search "Coverages" and choose the minimum area. Don't bother with countries you'll never go this year.
4) Is there a known metacode ? Most recent maps are 1155, 1150. Search "Full set of metacodes".
5) Then you can open TTActivator and select the right values.
