When I get to a destination, the nav tells me which side of the street its on but not the house number. Does anyone know a way get the AVIC-Z130BT to announce or better yet, display the destination house number at the destination?

There is no way.

I've been reading up on the navigation mods, maybe someone knows a way to mod the unit to display house numbers at destination.

What mods?

Well if you entered the house's destination address into it to find it, wouldn't you then already know what the house number is? lol

Unless you're searching by like PIO or name of business, when you goto search on it, it should tell you in the INFO button when it lists them
