Upgrading chartplotter

[SpongeRob]

My 2006 H33 came installed with RaymarineRC435 chatplotter.
It works well but very small screen and not as much detail I would like
Has anyone upgraded to a larger screen plotter and what did it entail.
Which makes and models were the best match for this model

Do you have the Navpod and other Raymarine instruments, i.e. wind, depth, speed, auto?

You may want to stick to Raymarine and the C80 0r C120 if they'll fit and your budget.

Garmin 3210 offers a large screen. It also offers split chart/radar screen.
