The first thing I bought a chinch (pic.1) to headphones (pic. 2) cable. Taken the glove box out and the Fiat radio. Fitted the connection cable and 1 two line cable for power (pic.3), had the hole in the dash when I bought the car (prob. a mobile phone holder) Connected the two line cable (pic.3) to the negative ( - ) cable of the car, and the other one to the positive ( + ) witch only has power when the car is running. So the power line has no constant power and the LED that shows charging of the iPod isn’t visible when the car is not running.

Then I connected the Sony 5700 to the car and inserted the chinch’s to the sony unit. (pic.4)
This is it for the Sony unit side.
Now comes the tricky part (so to say)
First I had to find out witch car iPod holder has the charge option and constant level volume output.
When connecting an iPod directly to the headphones jack (pic.2), the volume can be adjusted to a higher level from iPod and that can damage the amp. So I decided to buy PodGear CarDock Cradle & Charger (pic.5) (found it in MacWorld, bought it in Austria-closer to my country) - can find it on eBay for sure, regular coast in UK around 35£ inc. Vat.
