Yeah, I got the EX w/NAV. To answer your question, no. The NAV does not interface with the empeg. However, it doesn't interface with ANY stereo but the [horrendous] factory one. To me this is no big deal.

Forst of all, the only interaction that the NAV has with the stereo is with the voice directions. I drove around for a while with factory stereo and the voice on. For driving around town where you'll need directions every few blocks it was fine. For road trips? Let's just say that from Northern Virginia to Williamsburg is about a 160-180 mile trip. About every 3-5 miles there are exits. Imagine that at every intersection, a voice cuts into your music, softly telling you to KEEP DRIVING STRAIGHT, then your music comes blasting back again (this assumes you listen to your music loud ). Regardless, it's annoying.

So basically, it doesn't matter. The NAV system works incredibly well, however. It's VERY accurate, and it always gets a wow from passengers.
