Hoping there is still some life in here
Before i go any further, i promise, i have read the whole thread from back to front, upside down, and round about. I have connected the aux cable in the right slot in the back, i have soldered in a 300k ohm resister between L and R, and used capacitors too (2x on each in parallel as i origionally bought + - ones so swapped them out). But i am getting no where. I have run a multimeter across the L R to make sure i am getting resistance, and i am, of 300k ohms.
Basically, i plug it in, get FM / AM and CD but no AUX anywhere, ideas?

Any help would be greatly appreciated.
