hi guys, sorry but i need to ask this and theres no avic 80dvd forum because my navi is old. my avic80 is using the cndv50 software want to upgrade to the cndv60 disc. i have the 60 disc but when i put it in the nav, it says wrong disc. does anybody know if theres a bypass for this. thankyou all in advance!
