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

This card reader is vital 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 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.
