COMAND repair: Identify error pattern and system<\/h2>\n<\/div><\/div>

Is your Mercedes navigation system constantly restarting, stuck at the logo, or showing \u201cBootloader active\u201d? ProDiag Bremen offers repairs for NTG 4.5, 5.1, 5\/5.2, 5.5, and 6. The appropriate service depends on the installed device and the error pattern. <\/p>\n

Select your system below and compare the described symptoms. If you do not know the NTG version, send us an inquiry with the FIN and a description of the error. The model series alone is not enough for a reliable identification. <\/p>\n
