Hi all,
I have an mp3 player (no name cheapy) that I want to use via the head unit in my car.
I connected the earphone output (2.5mm stereo) to the aux in on the head unit ( 2 x RCA's) and it works as it should ie I can control volume, bass, treble etc via headunit.
The mp3 player is battery operated and is charged either by usb port on the computer or by a 240v adapter that the supplied usb cable plugs into (same cable for computer or charger)
The 240v charger is marked:- Input: AC 100-250V 50/60Hz Output: DC 5.0V +/- 0.5V DC400mA
I'd like to be able to power the mp3 using the car's 12v system but I'm unsure what input/output charger I need to put between the 12v source and the mp3 player?
I had a look at Jaycar's website but couldn't see anything that sounded right.
Can someone advise me what I need - other than a crash course in electronics :)
Thanks
