(not so) new car stereo renders speedometer inoperable

[Tom_Jane]

I removed the good cd player from my Barina and put an old one in and immediately noticed that whenever I had a cd playing the speedometer did not function.
It just sat at zero and didn't move. As soon as I removed cd the speedo began to function again.

The car stalled also. Possibly unrelated. It does stall once every blue moon.

Anyone know what is the problem here?

What is on the CD??

Problem could be the music you are playing or the badge on the front of the car......

I believe Barinas use CAN bus and the headunit is quite tied into it all.

I just took the runt out for another spin after ripping the head unit out and placing electrical tape in a few places in case it was earthing out somewhere.

I stalled twice more under these exact conditions.
-either cd or radio was playing
-coming to a stop
-indicating to turn corner while slowing to a stop.

Still, each time I had the radio or a cd playing the speedo fell to 0 and stayed there until I turned it off (the stereo).

I am not interested in spending more than a few dollars to fix this problem because I am trying to sell the vehicle.

Hypothetically, if I'm selling to a car yard will they use the fact that there is no head unit as an excuse to offer me bugger all for the vehicle?

Hypothetically, yes - a trade in without a head unit and a tendecy to stall will certainly put a dent in a vehicles trade in price.

Depending what type of value you want to put on the sell price, a check by an auto electrician could be the answer to your problems or you may consider not worth the effort and just trade or sell privately as it is.

No.
No head unit = no stall.
As I said it only stalls if cd or radio is playing.

Ok - easy fix, don't listen to any music and the problems fixed - otherwise it's off to an auto electrician to source out the problem.

I just threw the good head unit back in. No more problem.
I did want to keep it though. Bummer.
Concerning that a single CD player could cause all that trouble.
Thanks for your responses.
