Did you install the right-hand switches or did you have someone else do it? Either way, your 4Runner should be pre-wired as my 2003 SR5 that did not have ANY buttons from the factory was already prewired. There are only 3 wires leading to the NAVI on the small 20-pin connector. It sounds like the right side isn't connected properly or is just defective. The connectors on the ribbon are pretty flimsy, so I would start there to make sure they're connected properly. Honestly, the voice command is pretty useless, the only thing I could get it to recognize was "I'm hungry."
As far as your mic goes, I would buy the connector that the mic plugs into and then fabricate a harness.
I also added the AUX input (used the switch from the GX470) and have an aftermarket backup camera installed but haven't hooked it up yet. Fishing wires through the hatch is not fun.
Honestly, I would try to get it working since you already have all the parts. Why spend more money for something that you already have?
