Hi,

I've bought a Sony DSX-A40UI car radio. It has a rear jack for a Sony wired remote. I'm using it with an RM-X2s.

On the first head unit I had, the wired remote control worked for about an hour after the radio was turned on and then it stopped working. No response at all. You had to turn the head unit off and wait for a few hours before the remote worked again.

So, I took the head unit back for a replacement.

On the second head unit, the wired remote works for about 2 minutes after switch on. Same deal again. You have to turn the head unit off afor a few hours and the (wired) remote works again.

I've tried using the wired remote with an old Sony car stereo, and it works no problem, so that rules the remote out. Given these remotes are just abunch of switches and resistors, I'm inclined to believe it's the radio at fault.

Is anyone else having this problem?

The head unit works fine with the infared remote (even after the wired remoate has stopped working). Rest of the radio works fine as well.

Thanks.
