Upgrading GP7000FNT to GP1870F

Sales

Question

​I have a GP7000 and I am wondering if I can upgrade to the newer GP1870F. Is it compatible with my current external GPS antenna and Bronze 50/200 traducer used with the GP7000?

Solution

​Yes, the GP1870F can use the same transducer, power cord, and coaxial GPS antenna as the GP7000F/NT. Please note that the GP1870F uses the newer C-Map 4D charts.
