Interior
I need Aux input on my 06 Trailblazer LT. Since I searched radio modulators, GMPD12 was on the top of list. However, it cost $ 132. It is expensive to add just aux input.
I consider changing whole head unit. It's supposed to have AUX input, 6-7" touch screen, MP3, DVIX, XVID playback, USB or SD...
