Charging iPod w/aftermarket head unit?

I'd like to change my stock unit/USA Spec setup for an aftermarket deck since I'm upgrading the whole system, however I really hate to use the battery charging of the USA Spec. If most aftermarket head units link to iPods using the headphone jack.... how is everyone charging their units?

I use the iTouch to watch movies on long trips, and would like to limit to one cord out of the itouch rather than two!

 

Headphone jack does not charge the iPod. It has to be tapped in via power and ground and charged via the iPod dock port.

 

whats wrong with a the lighter charger?

 

Maybe I dont understand your question, but most aftermarket decks have an option for an iPod cable...ex http://signature.crutchfield.com/s_500CDA105/Alpine-CDA-105.html?tp=5684

The only thing to watch for is make sure the cable adapter for the headunit you choose is compatible with the generation/type of iPod you want to use. Some dont support newer/older gens.

 

they charge when they are plugged into the USB port of the aftermarket radio.

 

Not all do this.

My Pioneer HU charges my first gen Ipod, but the Pioneer I put in my daughters Jeep will not charge her Nano.

 

Thats prolly because she needs an adapter...some newer Gen iPods are switched from 12v to 5v. Google Scosche iPod adapter...in fact here:

iPod only charges when it has a USB power or tapped into the battery via power and ground wire but hooked up on the iPod dock aka the bottom of the iPod not the headphone jack.

 

my ipod is hooked to my pioneer through a USB that charges it
