I just powered up a panel upgrade today with a GRT Mini-X with the backup battery and the GPS antenna. Extremely easy install as a stand-alone backup. Only 2 wires (power and ground) and the GPS antenna. It fired right up and the EFIS came on with the synthetic vision and the map looked great. I'm extremely impressed, especially at the price point. I don't see anything else in the market that provides this kind of functionality for the backup $.
