TZT3 Charts

[Flyingfish]

I recently added a TZT3-12, I've been using a GP1971 which I still have installed. I have the Navionics chip installed on the GP1971. I much prefer the Navionics chip, Icons are larger, fonts are larger, contour lines are better. I know Navionics are not available for the TZT3 but are there chips available that are close to the Navionics. I'm on the East coast. Thanks

CMap is the only optional chart for the TZT3 aside from the free NOAA charts.
Linked here is a video on the way the charts work. The TZT line doesn't utilize "chips" the way your GP1971F does.
