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?

Did you ever find a way to downgrade?

Set the display scale to .1 mile. Do the roads display then?

No road their are fewer roads available on the new map set. Be nice to know how to downgrade
