463 COMAND with HDD/Navi-------------- 90200791

NOTE:

If a COMAND head unit (A40/3) with PIN theft protection is installed in the vehicle, the PIN code must be documented in the VeDoc system.

Observe the [initial start-up] instructions guided by DAS/XENTRY Diagnostic. During the SCN coding process, DAS updates the head unit

relevant data in VeDoc. All this documentation is done automatically by DAS/XENTRY as part of the SCN coding process.

You must complete the SCN coding process so that XENTRY Server loads and documents and correct theft-protection PIN onto the head unit,

other wise, the head unit will not function after 50 ignition cycles have been reached.

NOTE on Hard-drive operation at high altitude (3000 Meters or higher):

To protect the head unit's hard-drive (HDD) from being permanently inoperative, we specified the HDD to shut itself down as the vehicle (and

therefore the head unit) reaches an altitude of about 3000 Meters (9842 ft.) or higher with temperature around the head unit and its surroundings

reach 55锟斤拷C or higher. This condition is normal.

At that altitude and temperature, the Hard-drive music register, Navigation System, Voice Recognition, Gracenote Database CD/DVD drive will

not be available to the user. Once the vehicle is brought down to altitude lower than 3000 Meters, the above functions should return to normal

operation. Do NOT replace head units or the claim will be denied.
