I have an older Hatteras 53 that came with an ICOM MR-610 radar. It got damaged by a storm, and the insurance company said the value is less than my electronics deductible. I'd like to find a replacement.I'd like the same model, or at least one that can use all the existing cables. I seldom use radar, so don't need a "modern" unit but do want to have all electronics on board in working order. I believe all I need is the array, but would consider a whole system. So, did you upgrade and keep your old ICOM? If so, contact me. Thanks, Dave
