Yes, all of our system bundles include power adapters which automatically adjust to 12 or 24 volt systems. Each of our power adapters are specifically designed for aircraft usage. In order for a GPS systems to work properly, the voltage must be at least 10 volts or higher. XM weather units require at least 12 volts or higher to function properly.
Please Note: If your aircraft uses a higher volt alternator, the power adapters will allow up to 34 volt before the fuse will blow.
