hey guys, i know the ipod has been discussed a few times but couldnt find the answers to a couple of probs i have.
well i just received one of those Y cables. picked it up from ebay. they claim it charges all iphones/ipods (12V and 5V versions). plugged it in and it charges fine which is great. so my probs are:
a) why does the ipod sound so crap???? im not much of a audiophile (or whatever they are called) but i could tell the diff between ipod and CD (or radio for that matter) straight away. sounds a lot "flatter"??? is there anything i can do about this??? im ripping the music at 192kbps AAC. Im usually not that anal over the quality as long as it sounds half decent, but this sounded pretty crap.
b) the ipod charges straight away when you plug it in, and will keep charging (and stay on) when it is plugged in even when the car is off. Now this is a bit retarded. Will this slowly drain my car battery and should i be unplugging it every time?
