Can anyone who has used the downloadable Comand 2.5 firmware update please lend it to me to update my unit. I have downloaded the update and despite using two different types of CD's my unit refuses to update. It starts the process, gets to around 90% then stalls even after leaving the process running for well over one hour. If someone would loan me a known working disk i would be most gratefull. I would of course pay postage both ways. Thanks in anticipation.
