When I use my focus in my car I have several settings in place. I plug it directly into the aux in on my stereo with one of those dual cables. Works fine with other players but with the Focus the volume it too low. Most songs on the player sound ... okay but to get them there I have to turn the volume on the phone all the way up and the volume on my radio all the way up. Some songs are still a bit queit. If you play something thats more quiet by its nature, for example Pandora or Slacker radio there is no way to get a loud volume. Its like the headphone jack on the phone has been limited in its output. Like I said no other device I've tested hooked up like this has had any problems. My radio has a input level adjustment for the aux port but it is also all the way up. Has anyone else ran into this?
