I'm thinking about doing this. Can someone post some photos of what the external antennae looks like? Unfortunately the website doesn't have any photos of the system installed.

A few times i've temporarily had my plug and play running. Downsides are that being around NYC I had to change the broadcast frequency a few times and the loose wires, etc. Upsides are the external antennae worked fine inside on the dash above the central speaker.

Obviously the cost differential is pretty big, but it seems worth it b/c of the touch screen and always clear radio signal.

Couple other questions:
- Does this void any warranty?
- Does this install into the Aux input? And if so, can you not use the Aux input in the center consul for playing iPod type players?
