My problem is when i bought my 07 screw it didn't have the nav in it. So i had them put one in it for $1200.00. Yesterday I bought a zune Mp3 player and thought wow I can plug this in to my line in jack on the top of the dash. So I plug it in only to find there is no media line in on the nav unit. Does anybody have the nav unit with the line in media select on their nav unit. Or did they put an 06 nav unit in my truck? Pics would really help so can put it the managers face. thanks

you may have to get it reprogramed, take it to the dealership and tell them your problem, the should fix it at no cost.

 

that's pretty messed up... maybe an unpluged cable even?

 

I have a line in option on the screen of the NAV unit.
