Hi,
I posted this in general and got a reply from BorisM who said maybe someone could do a script hack for me. Anyone interested in working on this?
"I’m a new AVIC-F900BT user (Santa was good to me) in Brisbane, Australia and I would like to set my F900BT to avoid an area permanently. I can’t find a setting anywhere in the manual or system for this.
A right turn at the end of Coronation drive will be closed for 1½ years and it’s a major intersection used by the route calculator. The area is also not easy to navigate for alternative routes due to the volume of traffic etc. I can't wait for the new maps to arrive so that SUNA will be active. It might transmit that the area is to be avoided.
I hope someone can help. Thank you."
