Just got to the TSB section for your car and search for "PCM". You want the TSB that has "Installation" in the title.

I finished the install, everything seems to be working fine, except that on the map signal loses track every once in a while.

Is it in some kind of learning mode or do I have to reprogramme it with dealer?

Assuming you fitted a nav module and GPS puck and the puck is in a good location , the way it should work is the navi itself uses gyros most of the time and the GPS signal to correlate / adjust every few minutes. There are different versions of the navi module for 4wd cars so its important the correct nav is installewd and in the correct orientation (vertical versus horizontal). The navi and PCM talk to each other and should be matched in terms of software and hardware. If you know the part number of the navi module and the current software levels of the PCM (press main and trip together) then its possible to establish if everything is matched or needs updating.
