I've used the Honda Navigation system, and it works well mostly, but causes trouble when I'm using my CB / Intercom / etc.
I use Scenic app as primary - compatible with Google maps and Kurviger (remember Google has a 10 waypoint limitation)
I use Rever Pro app and website as secondary - route from website just shows up in the app and can kick out a GPX file formated for your Wing
Both support turn by turn voice with a paid subscription. Scenic has a lifetime subscription option.
Inroute is pretty good too.
If you are going to use Honda Navi and ACP Navi simultaneously, start up sequence for routing is ACP navi first (get it fully started), the Honda Navi. If you start the ACP navi after starting the Honda Navi route, the Honda navi will stop routing.
As for a Navigation system causing trouble with CB and Intercom...I assume you mean that Navigation talks over or during CB and intercom transmissions.
Use of ACP is not going to change that.
That prioritization is by design in both your headset and on the Wing.
Intercom is a lower priority than Phone/CB/Honda Navigation/ACP Navigation. All four will superceed intercom transmit and receive.
Where it gets a little strange is when CB, Honda Navi, ACP Navi are both trying to talk at the same time. What happens depends on which settings you have selected.
See listing from highest (top) to lowest (bottom)
There are settings that let the Navi speak by interupting or speak simultaneously. You have to figure out what works for you.
