My XMT unit is not working on my AvicZ2 after nearly a year. It says check antenna. I've check and it is connected properly seems snug.

Anyone know of replacement models that work?

Pioneer has one on the site for $67!!! but not available.

Any other options?

Part number: CXC4683 for the GEX-P10XMT

Any with the pink connector should work. They even sell them with the shark fin thing somewhere if that's your thing.
