I have the Avic-D1 (not installed yet), got my wiring harness all modded like the previous avic posts stated (adding wire to harness, and grounding pk brake, etc)

Do I still need to put a switch on the speed wire?

Thanks!

hah, Thanks. I actually used your thread for help, great info. I was just reading other thread about a switch.

OK no switch needed
