the sprint file is a zip and contains a .dll file called serial_btur_dm.dll which is the file that comes on sprint tp2 out of the box from what i understand. so if you never upgraded to a custom 6.5 rom, you should already have this file. if not, unzip this file and copy it to your windows directory using resco explorer or total commander. please be careful since once you over write this file and soft reset you will not be able to change back, so you might want to back up before you do this. my suggestion is to try the avic cab first with your current version of the serial_btur_dm.dll since you can always uninstall the cab. play around with it until it works for you, if it ever does
