Question lang for those who has ipods and are using it together with their head units. I'm thinking of upgrading my HU, preferably iPod ready HUs, hope you can help me out on this. Thanks dudes.

1. Brand and model of HU used with iPod?
2. Can you control and charge your iPod through your HU? Do you need an interface system for this? Is it locally available?
3. Problem/s encountered when using using iPod with HU?
4. Quality of music from iPod when amped through the HU? (5 highest - 0 lowest).
5. Conclusion/s (whether to use or not to use iPod together with car HU).
