It came without a battery at all so after checking if it turns on I ordered a new battery and a programming cable too.
Battery and cable just arrived today. I installed the usb drivers and everything. When trying to read the radio trought CPS (v9) i get the error "Read the radio information error!", i've tried also to Reset Default Data but I get the same error. From what I understood it might be password protected? And I have to update to the latest firmware then try Reset Default Data again? The fun part is that the fw on the unit is v1.00.00.461, and the lowest firmware upgrade kit I found was v5.05.05.022 but it doesn't work because I don't have older versions..

At the moment i'm a bit stuck and don't know what should I do next, i've also tried to read the data with an older vw version of CPS V2.02 but there I get "Failed to connect radio. Please check all connections and port settings!"
Any advice would be much appreciated, thank you!
