I took a Garmin 250C off my boat when I install the HB up front. I have the Garmin 250C, swivel mounting bracket, power cord, protective cover and the US2 cable to hook it to your terrova US2. The garmin transducer is still on my boat. I can remove the transducer but I would have to cut the wires and solder them back together. I tried to remove it but there are just too many wires for it to pull through without cutting it. If anyone is interested I will get some pictures tonight and come up with a price. It is a real nice little 2D depth finder. It is color and the 2D images matched my 898 2D when I had both of them mounted on my boat. They both picked up the same structure and fish in 2D.
