Does the Z120BT do turn by turn routing on all roads in its database, rural roads? I have used OEM navigation units that don't provide turn by turn navigation in rural areas?

I am not really sure what your are asking but I have never seen a navi that did turn by turn only on certain roads. What does it do if it doesn't do turn by turn?

On my OEM Chevy Silverado, when you get in some rural areas, the turn by turn navigation will end, and tell you turn by turn guidance can not be provided in this area, and tells you to follow the pointing arrow on the screen, which just points in the direction of your destination. I live in one of those areas where my OEM Silverado nav unit does this. Kinda defeats the purpose of having a Nav unit, since I think you would be more likely to get lost in a rural area, than a main road! All Garmin units I ever used will route you on any road in its database, just curious if the Z120BT did as well.

just curious if the Z120BT did as well.

It will do turn by turn regardless of which road you are on.

Thanks for confirming the routing on the AVIC z120bt
