Hello
I have a TT one XL with 4gb SDHC card that now has a current bootloader (5.5128) and navcore (9.510).
I downloaded and installed the wrong map "Europe_West_950.6544" - all worked fine but I really wanted "Western_Europe_950.6493" that's with ALG + IQR so I downloaded and installed that, but it would not work.
Tried Fastactivate on the new map and it said map was incomplete.
Compared map folders, and saw oldmap.meta.dct missing, so copied and renamed newmap.meta.dct to new map folder and ran fastactive again and it reports both maps now OK.
But TT one XL still refuses to switch to the new map - is there a compatibility problem with an old TT and the newer ALG, IQR features ?
Many thanks.
