You might be exactly right. When I talked to a HB rep today he didnt explain it to me that way. If thats the case, I might should just go ahead and get another 1199 for the front. I will give them a call back on Monday just to make sure and ask them that exact question. Thank you very much!! Im not going to interlink my 2 units anyway. All I want it to do is get a unit for the front to do nothing but operate the 360. I have an extra 1198 but I keep it for a back up for my side scan on my console.
