I am also desperate About my HDJ100 2004 NAV System.
Working on the pin60 issue did´nt Change the Situation , an Exchange of the platine also.
The screen is on, but first with empty datafields and no Nav or Audio and a/c Access.
(A lot of error codes at each Position of the avc-lan @ readout mode).
After About 30min, the Problem disappears, everthing works like factory new!
AVC-LAN Shows full Operation at all stations.
Stopping and restarting the car within some minutes is possible with a normal System boot, if the systhem ist cut off longer, it takes again 30-40min to normal Operation.
I am not able to understand this Symptoms.
A cable or connector Problem would Show other Symptoms, a loss of a single component also.
It´s like a defektive electrolyte capacitor anywhere in the circuit wich awakes after 30-40min.
Did anyone had the same Problem and found a solution?
Sorry , my german text corr. tool casts uppercase letters
