I recently purchased a X5 and I'm only getting locked channels. I was trying to upload the latest firmware but I seem to be having issues. There is too much on this site to go through looking for the right files, and I don't have the correct software to load it. I've modified a Serial cable to plug into the back but with out the correct software and firmware versions this doesn't do my any good. If someone could help get this working and some decent channels I would forever be in debt to you.
