Review on 📀 Efficient Multicolor Raymarine SD Card Reader and USB Port (A80440) - Simplify Your Data Transfer and Connectivity by Corey Bigglesworth

This card reader is crucial for updating maps and software updates, as well as storing files (screenshots etc.) that can be viewed on other computers. I have found this reader/writer to be the only way not to have to remove my Raymarine Axiom display to access the micro SD card slot for Navionics chart updates or software updates. I installed two units - one on the helm of the open flybridge, having good luck withstanding the weather and washing the boat.
