here is a Freescan file, 2.17, you will need an unzipping utility as RR requires files to be zipped. From the thread, it says you have a mac. I missed that , the file is a windows based file. you will need a computer that has a serial port , a computer that has a serial to usb converter or you have bought a usb to 396xt cable that is an option. All of these steps, are only done once so the learning curve has a minor step at first.
