iPod Connection to Standard Radio, is it possible?

Ive a ipod charge and play lead somewhere, it plugs inline on iso leads the sound is also great, I will dig it out once I get back home. Its better than using a normal fm modulator as it hard wires to the ariel connection. I wont return to my man cave until friday, I will give you details of that. I fitted an expensive parrot kit for my g/f with ipod interface so this was made redundant. I wont want much for it if I find it. Just trying to remember where I shoved it! Im sure these are cheap on ebay ect.

Thanks, please let me know. kind regards.

If after a new radio, Halfords have the sony models on offer, with bluetooth and ipod control.

However, since I bought one this week, the ipod control is no good, as there is no rear usb port, you have to plug your ipod charger lead into the front panel every time you use it.
I'd prefer a connection that was permanently leading into the glovebox or a dock somewhere.
The bluetooth is good though.
