Ok in my MJ I have the following USB jack fitted into the dash:
It connects to my pioneer head unit. I was just using a flash drive, until my wife got a new ipod, so I got her old one. By old I mean like 6 months ago and she just wanted a bigger one. The headunit can actually control everything from the USB connection, all ipod functions, so there is no need to buy the IPOD cord that actually connects to the back of the headunit.
Problem: The ipod is the skinny Nano, and does not charge from the usb jack in the truck. I assume that this is because the headunit only takes signal from two of the four wires, and does not send any power back, like my laptop does. The ipod does charge from the usb cord if hooked to my laptop. The weird thing is that it did not charge from the special ipod cord in her truck (she has the one that is specific to the IPOD and connects to the back of the unit).
Solution?: I figured I could splice a 5v, key hot source into the usb cord that is behind the dash, using the unused red and black USB wires. This should charge the IPOD correct? I realize that I need to filter it well and all that. I figure the easiest way would be to get a dc charger and take it apart so I have the actual guts and don't have to deal with soldering any contraptions together. Then I could just run some wires off the fues block, to a project box with the DC reg from the charger, and from there to the usb connection behind the dash, right?
Thoughts, comments, concernes? I was planning on getting another USB extension cord to mess with incase it does not work, that way I do not ruin the one I already routed. I am slightly worried about sending 5v back up the line to the headunit, but that may be unfounded.
