Any Way To Add Group Function To Je480?

[saaron]

I've recently got a new JE480 MDLP deck on eBay for a good price and read the manual and found there's no group function on it. Now, I'm not as concerned with not being able to create/edit groups as I've got a shelf system that can do that, but I was hoping that the player would at least allow me to navigate between them like my car deck does.

Does anyone know if there's a hack that can be used to switch on the function? I cannot imagine there's that much difference between the 480/780 (which don't have group function) and the 980 (which does) -- they all have the same remote after all -- so I have to think there's some kind of change in firmware or system board (a dipswitch setting would be the easiest to deal with!) that disables it that I could then change to enable it.

Has anyone got a service manual for this system or hacked them around?

Any info is appreciated. I've searched, but cannot find anything on the net.

The 780 does have grouping functions unlike the 480. I believe the function resides on the software PCB, but you's probably have to replace all the front panel (due to the added buttons of the 780). I'm studying the 470 service manual atm, but best would be to have the 770 or 780 service manual as well. I'm interested in exchanging the 480 display with the 780. Don't know if that is possible atm.
