In addition to the Actisense device, you can also check the Simrad AT10 for two way communication 0183 - 2000, a little less expensive (at least in Europe). I just bought it (with an additional Simnet - 2000 cable) and will install it on my next visit to our boat. This was recommended by Jose, from s/v Ipanema, and is working well for him.
