check the head unit holes & pins for corrosion. Make sure the connection is stupid clean.

*I use MAF / electronic cleaner & small fine wire brushes to clean up my junk when it stops wokring.

My Matrix likes a good battery too. I dunno?
I have/ had a love-hate relationship with two Matrix 17...
You may want to save the $85 head unit replacement for the Matrix and get a different unit all together.

$.02

If you were closer I would loan you my head unit to test your connection. Someone local might be able to help?

H-Birds are indeed hyper sensitive to corrosion of the contact points of the plugs.
Most everyone here is right, this corrosion will cause a flux in voltage, and the unit will misbehave.
indeed, the fuse in the power wire is a bit finicky as well. Sometimes on sometimes off.

Try cleaning the connectors super well, then using dielectric grease around them to discourage future corrosion.

Good luck.
