Not too tough to install. I had to access the back of the head unit (W200) to hook up to the remote out wire. Then tapped into switched power and ground. The signal travels via RCA (cables not supplied) to the aux input of the head unit. I wish it was Ai-Net, but no big deal. It's just that I'll need to get a video switcher now if I decide to reinstall a Playstation or other game console. The antennae are pretty big and obvious. They were too large to put on my rear windows, so I did the best I could on the front windshield. I'm convinced this works best anyway due to the dark tint I have on the rest of the glass in my truck. I stuffed the base of each antenna into the headliner and ran the actual stems neatly along the edges of the glass. Reception isn't great by any means. It's pretty much what you would expect if you took a TV and some cheap rabbit ears and toyed with them to get a signal, and then changed the channel. You can't adjust these to fine tune them for each individual station, so it's never "perfect". And while driving, the signal gets better or worse as you move and make turns. The higher channels work much better than the lower channels.
It's pretty much just what I expected, but part of me hoped for it to somehow be better. No dice. lol
It's neat to have, since I'm basically just loading up on all of the add-on gadgets you can put on a W200. It works well enough to at least listen to the audio for the news as I head to work. Same for important sporting events if I have to be on the road. And I suppose if I really wanted good picture from it, I could cruise around an empty parking lot until it looks good.
If it was expensive (it's not), or if you really want a great TV picture, I wouldn't recommend it. If someone knows of an external antenna that will make a huge difference, I'm all (rabbit) ears. Ha! Antenna humor.... sorry.
