New BB user here so watch out for the questions.

This may be off the wall but it is possible for the BB Curve since it can it can have up to 4G SD card and has a media player to connect to the car radio thru a 3rd party device so you can listen to your songs same as an Ipod would?

thanks...

i use a simple cable that has a headphone jack on both ends and plug it into my dashboard....works nicely

they cost around 1.99
