OK. I looked at the diagram and understand that connection does not work. For all I know, the jack(s) you are using could be outputs instead of inputs. I don't have a clue. Also, I only have the manual on FRF to refer to and, from what you write, your Concertone is different.
Never having owned and iPod, and without being able to see your iPod manual or the back of your Concertone, my assumptions are:
1) That your Concertone is fully functional and that you are able to set it to AUX input.
2) You have a stereo output on your iPod. This might be either a headphone jack or a dedicated AV output. (Different model iPods may have different output sources.)
3) That there is an AUX Input
connection on the back of your Concertone. See diagram #6 for illustration of two female RCA jacks at that location. (In some Concertones the RCA jack may be built into the back of the chassis instead of hanging loose on wires, as illustrated. Those might be difficult to see if you have not pulled the Concertone out of the cabinet. Also, they could be in a different location or not exist at all.)
If the above assumptions are correct, take your iPod and headphones to Radio Shack. I will use the headphone output to illustrate what I think you need to buy. Basically it will be a cable with a connector on one end that matches the connector on your earphones. This will probably be a male mini stereo plug but, in any event, the person at Radio Shack should be able to identify it. On the other end of the cable there should be two male RCA plugs. See http://www.radioshack.com/search/ind...0to%20rca&sr=1
The rest of the hookup is obvious.
If you use an iPod docking station, such literature as I have been able to find suggests that it has and AV output built in. In this case the connection should be from the docking station to the Concertone. So, if you use a docking station, also take it along when you go to Radio Shack.
Bottom line - Radio Shack sells iPods. Radio Shack sells component connection cables. All you should have to tell them is what kind of input connectors are on the Concertone.
Good luck and I hope this helps! I know it's frustrating but hang in there.
