My 21 year old Interphase 2801 depth finder is old technology. I'd like to replace it with a Garmin unit that will plug into my 2006C. If anybody has one or knows where I can get one, I'd really appreciate it! I just missed one last night on e-bay that sold for $102.50! I'm still kicking myself in the shins for missing it! I'll get the appropriate transducer, but I'd like to reclaim some dash space and get rid of the old unit. If anybody wants an old Interphase, let me know!

Thanks!!
