The PO told me he lost the navi button (along with the disk) and has no clue where it could be. I can't find one anywhere. There isn't exactly a plethora of wrecked G35's in my area. I've checked ebay and have had no luck. Anybody got a part number? Knowing Satan, they'll prolly want like $60 for the friggin thing. BTW, I use to deal a lot with Mitsubishi's MCAPS program. Is there an equivalent for Infiniti's.
