Anyone have an issue where the navi unit won't allow you to click on certain buttons in the navi menu? I have a bypassed n3 (used the switch) and everything has been working fine until i tried to upgrade my unit to cndv-80. i had some disc errors, but it didn't even look like it tried to install anything. ANd even after i tried the discs, when i put my old dic back in, everything worked fine. it seems like the unit is stuck in "drive" mode, even though it is bypassed, and even if i use my hot routes, it won't calculate the route. Any ideas?

I'm having similar problems. Regardless if the car is in Park or Drive. For some reason my unit stopped calculating routes and the bypass is no longer working. I also have the continuous display of the "viewing front seat vehicle prohibited". I noticed it for the first time on Monday, and nothing seems to work. Initially, in Nav mode, under System, I was able to see the "restore system". However this has since been grayed out (disabled) and I no longer have that option.

I'm using the original disc that came with the unit. The disc is in great shape and has no scratches, as it's usually always in the drive. AVIC-N3 is only 1.5 years old. XM Radio and Nav Traffic works.

Can anyone explain what is happening? How do I restore the system, short of disconnecting the battery?

Grayed out options...

The greyed out options make it look like it hasn't been bypassed properly. Check the wiring to make sure nothing has come loose

Thanks. I'll check the wiring, but I'm not sure what to look for as I did not do the install. I guess I'll start with the ground wire for the parking brake.

Looks like I may have a loose wire connection. Unfortunately, I really don't know what I'm looking at. I would be wiling to compensate someone with troubleshooting knowledge. Anyone in the NYC/Queens area willing to come take a look at it?

OR if someone can recommend a good shop. I'm willing to travel.

Loose green wire ground connection. Everything is working again. If the green wire is not grounded properly, the Navigation routing, NavTraffic and video will not work.
