Hello everyone i'm new to the sites.

I swapped out the leds on my dash, added a nav cluster with a custom screen, and an alpine radio. Everything with the install went great but now my tach and speedometer won't work. Does it need to be reprogrammed or is there something I can do or check to get them working again?

The units power up fine it's just the needles that don't do anything.

 

That's really vague. What exactly did you do, electrically?

 

Sorry if I wasn't clear.

It's a 2007 R56 base. I purchased a speedometer on ebay from an r56 with navigation. It didn't have the factory screen so I purchased a 6.5" touch panel and retrofitted it to the opening. The screen and pc works independently except for the 12v it gets from the car.

The alpine radio was installed using the BMRC-1 module and it's working fine.

The tachometer just had the led's replaced. I should note that it's possible that my father started the car without the tachometer/speedometer installed becaue he was installing a clutch and I didn't specify to him not to do so.

 

It's a general problem with installing a used speedometer from a different car. When a speedometer is initially programmed, it becomes permanently linked to the VIN because it's one of the places where the odometer value is stored, and AFAIK can't be reprogrammed if it's in a different car. So now you have a speedometer that is still configured for the previous car. I don't know if there's any way to make it work short of purchasing a brand new, unprogrammed speedometer.

 

Thanks for the help. I figured out the tachometer it was the needle was "too tight" and not spinning. After resitting the needle it is working perfectly.

As far as the speedometer everything on it (the warning lights, fuel gauge, etc) works minus the mechanism that moves the speedometer. I followed a thread here where he did the exact same thing I did except he states his worked perfectly.
