I purchased the Navionics card from Amazon. After I purchased it, due to some unforeseen circumstances I wasn't able to start the installation process for approx. 2 weeks. When I had trouble installing the software, I contacted Navionics for help. It took them 2 weeks to finally determine I had a bad SD card. During those 2 weeks I was asked the same question numerous times, provide screen shots, provide photos of the SD cards, did I try this or that they had asked me to do before. Finally, they told me to return it to Amazon where I purchased it. Even though it was 2 days after the return policy Amazon provided a replacement. That time the SD card adapter came without the micro-SD card; therefore, it was worthless. This time Amazon would only provide a refund. Obviously, Navionics quality control is non-existent, and their customer service is TERRIBLE.
