and the dealer included the Satellite install, so I took it in for installation ...
err... I take it the original model had no satellite when you purchased it in the first place. I'm only asking 'cause mine had it pre-installed (6-cd + sirius sat audio system, no audiophile). which leads to the conclusion that they've been working on it and apparently did a really lousy job. a REALLY lousy one. maybe addressing this directly to Ford would be a good idea, since they don't usually like being represented by unskilled bricklayers who call themselves 'authorized service points'. that, if you want satisfaction. if you want results... I'd take the car back and jam their door with it until they cough up an unscratched AND working audio system.
now for the tech part, (it's only common sense assumptions, don't DIY based on them please!) the aux jack on the console must have some connector that allows for the front panel to be removed. if this is the case, it might be really easy. if you have SOME volume FROM the iPod itself, then it's like you have a 'cold' wire somewhere or the ground wire connected wrong or loose. if you have NO volume from the iPod, it's definitely worth looking along the line from the dashboard to the audio system entry. if that is working properly, the next logical step would be to check the selector (radio, sat, cd, aux) and see if it's wired according to the plan.
finally, I only hope that you have a genuine Apple iPod and not a clone. usually Asian clones of famous devices use different impedance outputs, thus not being able to work with common 'line in' appliances. now 'line in' is a forced term, since the real 'line in' (or AUX) input you would see on a high-end, say, amplifier, uses completely different parameters for the audio signal - most notably a fixed volume signal, among other differences. this simulated 'AUX' we're having is actually an input able to use a signal designed initially for headphones (common 8-ohm impedance and variable signal). just as an example, I have an Archos pocket video recorder and I cannot use it in the car, whereas the iPod would work just fine.
(note: if anyone knows better how to explain these please feel free to do it - I'm a self-taught geek and I don't take credit for 'knowing them all'. maybe I've done some slight mistakes in terminology. but basically this is how it works.)
anyway, keep us posted... it's an interesting problem (wish you didn't have it in the first place) and it's worth knowing how it eventually turned out for you. and wow, what a huge post![8|]
