An XMFanStore.com Exclusive!
This small power adapter will automatically turn your SkyFi or Sony PNP
radios ON when your vehicle starts up. This adapter is easy to install and
requires no tools! When this adapter senses your car has been started, it
sends an IR signal to your radio telling it to turn on.
Important: You must have an ignition-switched power source for
this adapter to function properly. If your radio stays ON after you turn
your vehicle's power off, you do NOT have an ignition-switched power source and
this adapter will NOT work for you.
