Heres the steps i've got from another thread: Little tricky to do though
1) find the "in car tools" in the trunk, in the tire jack kit which fits next to the spare. They are easy to miss.
2) use the rods to push back through the holes. Use lots of force.
3) this will loosen the clock display. then you'll need to jiggle it and pry it off.
4) then eject the old map dvd.
5) turn car off.
6) remove fuse #4 (TV.1 or something like that) from the fuse box right above the parking break pedal.
7) turn car on. (it'll complain in english and japanese that the dvd can't be read.)
8) insert new map dvd (in my case the patched 7.1 with 5.1 loading.kwi file). It will take a minute to load.
9) put clock cover back on, and you're done.
The hardest parts are: 1) finding the "in car tool" picks; 2) prying the clock display off; 3) prying the fuse out of the fuse box.
Remember, all your stored nav info will be lost when you do this - you're starting from scratch again.
You need to put the #4 fuse back in before you turn the car back on. Not that any of you wouldn't figure that out. Also found that a small pair of needle nose pliers worked best for pulling the fuse and then you can use just your hands to put it back in.
Oh and one more thing. Do NOT use a DVD with a self-applied label. It will heat up and start coming off and potentially ruining your NAV.
Good luck!
chears thanks for the info but Im stuck at point no 4
