listen to his personal music from ipod in his vehicle with only jacks ... it was doable except that I had to pass the headphones jack of the iPod for this and in the end the connection, which should not be great either quality, did not last long, and I found myself to be in the old days with Walkmans to move the wire for the stereo .. (bad memories!) suddenly with this connection, I should not meet the same bp ... A test on the long road of the holidays!
