I had the alternator on my 2003 done last week, but today i went to use the sat nav and the location was not updating fast enough for it to work, so i checked the signal in the engineering mode and all fine seeing lots of satellites and seeiing my mph on the Gps, then i checked the speed pulse and this wasn`t working at all, not seeing my speed or anything. So my question is does, anyone know where this gets the speed pulse from? and any ideas what the garage could of knocked or done for this not to work?

Was it upgraded from RNS-D?

The speed signal comes from the dash, so if your speedo's working then I'm confused about why your nav isn't getting the signal. Perhaps trace the wire?

Yep was upgraded from RSND in Feb 2007 by Craig B and has worked fine until last week when i got back from having a new alternator fitted. Everything on the dash works speedo etc. I`m just really confused as everything else on the unit it working fine, its as if the speed pulse is turned off, is there anyway to turn this on or off?

Not unless you put a switch between the dash and the RNS-D which is what I did.

I'm assuming you took the GALA from the original RNS-D harness.

I'd try to get hold of craigyb himself in that case. I'm sure he wouldn't mind spending 2 minutes letting you know what it could be. Would probably tell you what to look for straight away. Maybe something got reset/lost when it lost power? Worse case, something got sliced or snagged.

When i look in engineering mode, on the nav sensor info there seems vehicle signal says its off, is it possible that if anyone can look at there rnse in engineering mode and see if thats the same on theirs.

thanks

heres how mine looks at the mo,

You are telling everyone where you car is located at the moment

Also, I'm no expert but I would presume that the "OFF" on the screen is refering to the revserse switch signal, not speed.

opps ta

When you drive the car with the engineering screen up what happens to the pulse count and speed numbers?

Nothing, stays the same.

Does sound like the signal's not getting from the dashpod to the head unit. Bit of a mystery as to why that would be though. Perhaps pull the head unit out and see if there's an obvious problem with the gala wire?

All done and working, i removed the unit gently, then i noticed 1 wire on the back that was hanging there all on its own which which had the metal connector on the end and had come out of the connecting block that plugs into the unit. On top of the unit it tells you what pin connector should connect to, and the no.3 pin was the vehicle signal and this had the wire missing, so pushed the lonely wire in the connector block, connected that to the unit, had a drive round and its all come back to life. so you were spot on Shoppinit. The only thing that i don`t understand is how this come out, but who cares its all working now.

Thanks again
