Mine is updated! All 5 systems
And I had no problems with the rs232 updates
Each takes about 3 minutes once you hit start.
The cross cable I had is the exact one suggested by Pioneer in the MCACC software manual - Belkin Pro Series Direct F3B207-10 ft. Has the same pin-out that's shown in both the service manual & MCACC software instructions.
If anyone is having problems with the cross cable, the Belkin one does work.
Now I have the pain of re-doing input setup & calibrations. But I'm happy it's finally done. This has been bugging me for well over a year & it took Hkan and the mass interest here to overcome my DIY concerns.
I just hope everything works
