Hi all,

I have a Furuno GP-1870F Sounder/GPS combo with C-4 Map. I'm not happy with the map quality and accuracy.
Navionics Platinum are impressive in their accuracy and detail, and I'd like to get a second 7inch stand alone unit that will take a Navionics Platinum card.
I have a through hull transducer and love the sounder function of the current unit, so no need to replicate this with the new unit.

Any suggestions regarding brand and unit for the new GPS?

Thanks in advance.
