These kits are still available. I ordered mine last Wednesday and got it on Saturday. Did the install yesterday in a little under two hours and it is great! No more dealing with sun spots interfering my FM transmitter or another person on the same freq!
I highly recommend this install, super easy and gives a noticeable difference in sound quality. Instructions I would rate a 8/10 and as far as customer service goes I got my package from Jazzy in two days! I would recommend getting your cables from a place like Monoprice.com though, he charges $8 for a cable that you can get for much cheaper elsewhere, just looking out for the financially minded! Thanks for this necessary mod Jazzy!
