I had a 8gb card in my Curve 8320 which worked perfectly and I play music through a USB input on my head unit for my vehicle a Pioneer Avic.

With my 8320 this feature worked great, now with my 8900 when the car stereo is reading/playing files from my phone it is constantly stopping or pausing.

It stops for a couple of seconds sometimes more and then begins playing again.

Up until today I thought it was sporadic, however I did notice today that as I touched the phone to bring up the home screen it did cause it to pause also.

I am hoping that I can re-format it on the new phone and this will fix my issues. Any advise would be great.

I will keep you posted to see if the re-format helps.
