If you have an alpine head unit with dvd and want to use it while you're driving thie is what you need. Peripheral PTR-7. This piece replicated the use of parking/foot brakes to engage the DVD feature and in-depth menus on your screen. It was originally created for the marine indutry since boat's don't have parking brakes.LOL

Anyway...if anyone wants this part send an e-mail to Todd Borden at Audio Synergy- synergydelsol@yahoo.com
They have 40 of them in-stock if you want one.
