I upgraded my 900BT with the new firmware 3.020 and am no longer able to get in to testmode. I have tried several SD cards and it still won't boot up in testmode. I have been told that the key set for 3.020 is not known yet. If it is not possible to get in to testmode with 3.020 is it possible to downgrade to an earlier version and still use the updated maps?
