ok, you cannot get the radio/navi codes from the vin number. you need the radio serial number and the navi serial number.
first look in the glove box for a white sticker stuck to one of the sides. there should be the codes listed or the serial numbers. if the codes are there enter them using the radio preset buttons and the knob for the navi. if just the serial numbers are there then post them here and I can get them for you.
second look for a white card with the paperwork that will have the codes on them
last you will need to access the number electronically. let me know if you need the procedure to do that.
