There is an antenna, and it is probably in the glass, but could be sitting alongside the NAV & Satellite antennas in the roof. It's irrelevant where it is, what's important is how it connects to the HU. If you take the dash apart, you will see a million wires going into 8 or so pin connectors that connect into the back of the HU. This is normal for all stereos, however, this is the first time I DON'Tt see an antenna wire, which is a large round connector that connects directly into the HU, not thru one of the pin connectors. I'm wondering if anyone has identified which of the many wires is the antenna wire, so that I can buy or make a connector to convert it so that I can plug it into my aftermarket HU.
