Hi All,
I've been looking around the forum for a while to get some info on upgrading firmware on my RNS510. At the moment I can only use 2GB SD cards. I have tried holding the setup key for 20 seconds (a lot longer actually) but cannot get the version number of the firmware to show. I just get a screen showing the AM/FM/DAB menu.
Anyway, I look forward to picking your brains sometime soon!
