Hello! I have a Toyota celica 03 GTS and I just got my AVIC Z120BT installed from the shop. On the way home I was trying to do some settings but found out that the I can only control "AV Settings and AV sound settings." The other settings are all dimmed and I cannot click on them. Also, I cannot even use navigation the only thing that I can use in destination panel is "POI History and Favorites." What do I have to set something up first to make them work? Or the shop that installed my system didn't hook them up right?
