Power source only on when radio on?

[bacara2]

Hey, I'm going to be installing a new head unit next week and as part of that will be installing a Netgear Push2TV to use google maps on the screen. I can wire a USB adapter like this one to power the Push2TV, but this will result in the Push2TV being on all the time the car is on. Thoughts on easy ways to wire the Push2TV so that it's only on when the head unit is turned on? The headunit is a Pioneer 4000Nex and the input for the Push2TV is 1.0A at 5.0V.

The only idea I could think of for this would be to add an on off switch that I could operate independently from the radio, but again this doesn't seem optimal.

Thank you,
David

I only took a quick look at the Pioneer manual, but it seems you could use one of the two USB rear ports, rated to 1.6A, 5V to power your PushTV. Am I missing something?

That's certainly the easiest option but the PushTV only outputs HDMI so If I use one I'll lose lose an input. This may end up being the right option, but if I can have two USB inputs I'll like to.

Ah, I see what you're saying and that should work. I'll look around for the right relay. Thank you.
