Here is a perfect good 334C that has all the cables, lake card, and transducer.
It came off of my Avalanche. The transducer mounting ear is broken off but may be able to repair with epoxy.
This unit works perfectly and I hooked it up thru the network of my HDS8 and LSS-1
Also includes the Ram mount.
Yours for only $200 cash at my door.
