I've currently got a 3G 15gb iPod, a 'plain' iTrip, and a 12v charger. I'm going to Ireland in June, so I'm thinking of getting a 30gb 5G because 1, my current battery life is around 3 hours, 2, I need something to store the photos I take on, and 3, it would be nice to be able to watch a movie on it. I also do a lot of volunteer work in an area where there are ZERO good radio stations. So, I use the charger and iTrip to supply music. However, the way I understand it, I won't be able to use my current iTrip (the one that plugs into the top of the iPod) with a new 5G. What transmitter WILL work? I'm very happy with the quality of my iTrip so I hate to give it up, but if I must I must. Also I'd like to save $20 and be able to use my current 12v charger (just a plane jane rig that looks like a phone charger, 12v on one end, dock connector on the other). So, what do i need? thanks!
