So it's been 4 days since I experienced this issue, whenever I plug my iphone into my ipod/USB port it charges it but won't read the music files. Screen reads "No music error". Has anyone else had this issue with their IS? Thanks.

 

I havent had this problem on my IS but I did experience it constanly on the hs20 loaner I had the other day. I would have to stop, power the car off and on again and it would work again. I dont know why it happens. Take it to the dealer and let me know what happens.

 

I have tried turning the car off, doesn't help. I thought it was my phone but it works on my other car.
