Thread: using a mixe of HERE and TT maps possible?

Yes, it should work. I use TT 2015.06 maps together with the 2015Q2 POI's plus extended POI's (did not update yet)

I was convinced my buildings were HERE origin too, but checking just now pointed out it are TT 3dc/3dl. However I am pretty sute the HERE buildings are as functional as the TT buildings in combination with TT maps. It should also work the other way around.

Edit
I forgot to write that you can even mix HERE and TT POI files in one map. They will show double on screen when a poi is in both.
