LMS-300 work for you? Have one from a boat I just bought to re-sell.
Still Looking....
I hadn't really thought of selling it but I have a LCX-27c in the box with all the parts. It's seen a few seasons but still works great.
Have the navionics gold card for it as well. I guess for the right price just about anything is for sale...make me an offer and I'll consider it?
