Hi all, first post in the forum, meant to share my experience and thank everyone that helped out.
I have a AVIC F900BT, had version 2.009 since I had updated from pionner just a while back (original maps)
Did as written in the first post and everything worked out great. (I just backed up all my orifinal files first, just in case...)

Just had to erase a few countries due to limited space.
Anyways, just wanted everyone to kno
