I just bought a used RNS-510 part number 3C0 035 684 A. The seller had upgraded the firmware to 1140, and everything works but the satellites. It can't see any. I'm thinking its the upgraded firmware. Does anyone have or know where I can download the original factory firmware, version 0320, according to the sticker on the unit.
I'm hoping if I restore the factory firmware that the unit will work properly again. I'm not looking for all the improvements that the later upgrades give, I'd be happy just having the unit work as designed from the factory.
