What is the 7495 calling the PCMCIA card?
Thanks,

I did the patch but it didn't seem to fix the GPS. I went to the adjustment screen to sync the unit with GPS but GPS icon stayed yellow. I also added the license patch but when rebooted it didn't show any new options. So I thought I would try it again and now the unit boots up and hangs on the Copyrights screen. How can I recover?
Thanks

You need to replace the elgato binary with the original, and start over. The only thing I can think if the patches didn't work, is you started with the wrong version of the binary (e.g. you did not upgrade the firmware first).

Whew! Found a copy of A.06.25 FW, put it on a CF card and installed it and the unit is back to original performance. So the patches did not appear to work for me. I went back and installed just the license one but no new options appeared. If I do the GPS one, unit appears normal but if I try to go to the GPS adjustment screen, it hangs. But I did see the GPS icon go green at one point! I was using the date command to set the time/date and maybe that got it to go green but as soon as the FW changed the time it went yellow. the saga continues...

Let's focus on one thing at a time.
Remember, for the license hack, you have to also modify the license file for each license you wish to add. The trick that the patch provides is that the key isn't ever read, so it doesn't need to be valid. Perhaps you are not doing this step.
Once you have done the GPS patch, you do not want to be setting the date/time manually. The date/time will be set properly by the GPS. At the very least, you can use the web interface to set the date/time once, using the date/time of the PC you are browsing to it from. If you ever have the green circle, then you are in a state where you can do the timebase calibration. Note you probably want to have the unit on for some 30 minutes plus, and you want to make sure you have at least 5 or 6 satellites locked.
