I have a wireless Flight Deck computer that is working erratically now. It worked fine for about 6 months and now I'll be on a ride and it will stop or it start to display nonsense. I've done the following things:

1. Replaced both batteries (transmitter and receiver).
2. Checked the spacing between the magnet and the fork transmitter.
3. Checked the angle of the transmitter to make sure it's pointing at the computer on my stem.

Anyone else had similar problems or have other suggestions?

Thanks in advance for your help.

I'd check out the contacts between the head and it's "nest".

I cleaned the contacts thoroughly and the initial indication is that fixed it. Time will tell if this fixes it for good. Thanks.
