Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

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.

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

I installed a new sound system in my relatively recently acquired 2001 996 Carrera 4. The mileage and digits appearing within the tachometer were in km (I live in Canada). After disconnecting the battery during teh installation, those numbers are now displayed in miles. The lever for the OBC works when I move it up-and-down and changes the values appearing within the bottom part of the odometer (see the picture). However, when pressed outward, which is supposed to activate the OBC, so that you could go to the setup and change various settings does not work. Am I missing a trick, or there is something wrong with the system? Thank you for your time in advance! Zack

From another user on another post "Page 74 of the owners manual. Dial with the clock looking face is turned to the left for 5 seconds to change speed displayed back and forth. " Don't know if you tried that to change back to km, or if it will fix the other issue. Zak

POST 3 / ORIGINAL POSTEROriginal post

Thank you Zak; will give it a try tonight. Cheers, Zack

POST 4Original post

Have you tried it with the engine running? Maybe ~9 volts isn't enough to get it excited?

POST 5 / ORIGINAL POSTEROriginal post

Hi Zak: The procedure you mentioned worked; in that, I could change the mileage numbers to be displayed in km. However, I could not still get the OBC activated, with our without the emgine running. Could anyone please suggest a trick to get the OBC functioning? Cheers, Zack
