Hey everyone,

I have a problem that I can't seem to find any info about. I have done searching with no luck. I added an OEM navi to my I30 as others here have done. Everyhting was fine until I started to lose the VSS signal.

I tapped the VSS signal behind the cluster as required by any navi equipped radio. Shortly after the install I started to lose the VSS signal after about 20 mins of driving. Sometimes it would come back on its own, other times it would be lost for a while. Sometimes when the signal was lost I noticed that turning on the car's lights would start the VSS signal again. However, that tricked no longer seems to work. I am not sure why this worked, except that maybe the wiring harness is bad (?) and b/c the connection for the lights and VSS signal are in the same harness, that triggerd the VSS signal?

I have checked the connections and they seem to be fine. I have also switched out the navi controller portion of the system and the issue remains. Although I have switched the navi controller portion, I am using the same faceplate b/c I painted it and want it to match (the face is removeable by removing a few screws). Could the faceplate be the issue? Oddly, it hasn't had the VSS signal for two weeks and last night it started to work again.

I guess I need to:
- recheck the wiring and connections
- try the second faceplate
- check the wiring harness for damage

Any experience with this, or other suggestions? I have removed the system so many times to troubleshoot, etc. that I am dreading doing it many more times. Thanks in advance.

 

Definitely a wiring issue, loose connection somewhere.

 

Thanks, do you think it's in the harness? Seems odd that turning the lights on (which illuminates the navi's lights and changes screen color) would affect the VSS signal.

Thanks again
