My car has an aux jack and I want to connect my iPod. When I plug it in via regular 1/8" wire from the iPod headphone jack to the Aux jack, it sounds ok, but I have to put the car's volume on max, so if I accidentally switch to radio I blow my ears out. What do you recommend for the best quality within a reasonable price range? (Also, it'd be cool to have some kind of car charging solution as well). Thanks!
