so i attempted to update my mk4 nav OS to v.27. I downloaded the software, unzipped it with tugzip, burnt it with alcohol at low speed (4X). i went to my car, turned the key to the first position, waited for the nav to boot up, took out the nav cd, put the v.27 in. Then the screen had some message that the software was being updated, and it went blank for like 5 minutes! i waited but still nada.. i tried pulling the cd out to retry it but it wont spit it out now.. my screen goes to the menu but its grey and theres no navi option.. what the heck did i do and how can i fix this??
only possible thing i can think i did wrong is: the cd wasnt high quality enough, and maybe i should have unplugged the nav tv unit from the system? i dunno, please help guys !
