W205 Audio 20 Head Unit gone 'in a loop' need help
Hi,
I have this problem on a W205 Head Unit that keeps rebooting and I have no radio, camera etc., From reading the forums it seems that I may need to re-flash the head unit. Xentry diagnose picks this error: B227d00 The Watchdog function has ddetected an internal software error. Is there a way of Flashing the head unit 'off Line'? I have access to SD4 Connect, Xentry, Monaco,etc OR can somebody do it Remotely? Thanks in advance |

C4 doip, ecom or bmw enet + monaco + some knowladge may do the job
If reflash won’t help - its easier to replace then repair. Audio20 is cheap -Pin for maps Ntg 4.5/5/5s1/5.5
-Comand region conversion -Remote coding/programming -Vediamo 5.1.1 passthru |
