My major gripe with the Z1 was no ability to search for an intersection. Does the Z3 add that ability? I've seen a post on here saying that it does, but I haven't seen it. Can anyone confirm?

Good question. I'm sure z3 owner will confirm, i don't think its possible.

Good question. With my Avic-D1 I was able to put the street in, and click the button next to it to put an intersection... havnt found this in the Z3 yet which is annoying...

Nope
