Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I am installing the new pioneer touch screen dvd in my new 03 tt, this is second unit I am doing installation with. There is a "speed pluse wire" which I need to connect to the nav unit, but I just can't seem to find it. It ususally hides behind the radio head unit in other cars. I don't know anybody here had any experence in installing aftermarket nav unit, if so please shine some light on me. I just need this to complete my project. Jacky Thanks in advance

can't you just fool it with a jumper somewhere? I know you can do that with the alpine one.
