I have the AutoLink AL319. I downloaded the update (2404061882ge.rar). I'm a little confused as to how to apply it, and does the system use a "rar" file, or does that have to be uncompressed? When I've connected my AutoLink to the computer, I'm also getting a communication error like it needs a driver or something. I did install the software from the included CD, but it did not include any instructions.
