There is a grey/pink in the radio harness which is the speed sensor and is used for the radios auto volume adjust (like the Lotus, which increases the volume as you increase power or accelerate and brings it back down to normal level as you level off the power).

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

  • Rennlist: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Hello all, Planning on putting this unit in my 99 c2 tiptronic. Does anyone know here the speed sensor wire is or the speed sensor itself (or if the car even has one) Apparently the unit needs it to run some of the mapping/charting functions of the gps/nav Has anyone had to find this wire in installing this or other units? does anyone have any guidance on actually doing the install (from experience or otherwise!) thanks in advance! -Dipak

POST 3 / ORIGINAL POSTEROriginal post

to be honest, I do not even know what the obd2 is......

POST 4Original post

Dont know if 99 has it but it is in the 04. There is a grey/pink in the radio harness which is the speed sensor and is used for the radios auto volume adjust (like the Lotus, which increases the volume as you increase power or accelerate and brings it back down to normal level as you level off the power). If it isnt in your harness it is at the fuse box and there is multiple points for the junction of the grey/pink speed sensor there. You may have to go to the dealer and have them look for it on the schematic for your year. For the AVN 2454 the speed pulse is used to trigger the navigation system and calculate trip time. And the reverse hook up is calculated into the trip time too.

POST 5 / ORIGINAL POSTEROriginal post

thanks all ended taking it to a knowledable installer in the area figured i wanted an "oem" installation i will post pics when it is all done thanks again
