How do you bypass the parking brake on a clarion VX400?
Hello. Bypassing a parking brake on a newer Clarion radio
(vx400, nx501, vz401, vx401, and vz709) requires an interface. You
can not just ground the parking brake wire or put in a code...
people that tell you this are wrong. The least expensive, smallest,
and best quality i have found are on http://microbypass.com. I am
an installer and i use these all the time. The company also sells
them on Ebay too.
