I have an AVIC Z130 that I upgraded to Z140. Now when I do not have a destination set in the Navi no roads are displayed. I see a map and the GPS function seems to work fine, but no roads are displayed on the screen. If I set a destination then the Navi show the roads? Any ideas? I don't remember this being an issue before I upgraded to the Z140. I there anyway to downgrade the software back to the Z130? Can I manually install the software through "File Maintenance" or some other way? Is there away to reinstall the Z140 upgrade?

Both the touch screen and the external monitor are black. The touch screen does respond to touch, but has no video, it's totally dark. Any ideas?

I installed a used AVIC Z130BT on my car. Everything worked great. I attemted to update firmware and maps and I had a problem. Now I do not have any video output on the LCD, or out the rear output video jack. The HU is functioning. I can play iPod, DVD, audio CD etc. I can load SD and VC works. But I have no video at all out any jack or port. I checked the cables to the LCD, and I have checked everything I can think of. Can anyone help - Please? Chris
