PM2 screen

[Manz]

My PM2 screen works fine until I insert the plug that connects to the heart rate monitor under my seat. Anyone else have this problem and solved it? Thank you!

Have you checked that the cable to the HRM receiver doesn't have a short-circuit? It's only a stereo extension cable so easy to replace if faulty.

Worth a ten buck punt.
