Does anyone have the TV Tuner unit for their D1 ?
Is it worth while ?

I have the TV Tuner with my Z1. Install was clean, infact the the install for the antenna along the perimeter of the windshield looks ominous a bit like a super sensitive shock sensor for glass breakage. If you live in a major metro area, you will be ok with getting some of the big three TV stations. Its a bit fuzzy at times, but mostly ok. I got it cause I sit in traffic ALOT on major interchanges between freeways in the Bay Area, where there is good signal. DO NOT buy this with the expectation of getting clear reception more than 50% of the time. Hope this helps!

I have this unit, but yet to install it. I am finishing up a custom dash surround install kit, which I will have manufactured for my old school Audi.
