there is a known issue with the software and mercedes is working on making a software update. here is the internal message we received

Do not perform SW updates via Xentry on 205 Audio 20 HU: Currently there seems to be some incompatibility between Audio 20 Head-Units and the Xentry machines. When attempting to update the SW the radios might get corrupted. Currently the only known fix is a HU replacement. To mitigate the request for Audio 20 HUs, please do not update the Audio 20 on 205 vehicles while this topic is under investigation.

so i would call the dealer and keep checking back for when the new software becomes available.

Lou
