the mk4 work but it is slow on startup....when i open the door the bmw logo doesn't appair at the same time i open the dorr but after 20 second and more.. the boot of navi seem so slowly..after logo appair the words: wait please for more second too..the navigation is ok after boot...

what i can do? if i turn off the battery for some minutes the situation can become better? there is a way to reset the mk4 after installation?yesterday it doesn't found the dvd too...i'm sad!!

Are you using a copy of the map DVD or an original? If it's a copy (your own backup of course) then it may be that it is only just beeing read by the Nav Computer, try an original - even an original CD Map from your Mk III would do.

i'm using a copy..not an original dvd...

thanks for answer...so you think that can be a problem of dvd map, not of the mk4 navi....

but why the screen logo doesn't appair at the same moment of open door like before with mk3? it can be really a problem of map dvd?

[dragone320d]

Try Downloading the v26 or v27 from the forum and installing it onto the computer

Perhaps, The installation is messed up

Good Luck

i have tried with cd navtech 2006_1 (only italy) and now the mk4 works fine..thanks for answer..now the only problem is when i switch from gps and tv and viceversa..but if i choose the av channel there aren't problems...

Have you set the country setting for the TV tuner? It's an option from the menu, can't remember exactly where.

yes, but i can't resolve the problem whit this way..only if i switch from the av channel or from ntsc system (we use pal)
