I did a test install of my new Kenwood KDC-X692 yesterday, which works fine except for Phatbox, which does not work at all:
I used Phathack DMS Tools to install new firmware for Kenwood (13.01 hacked, with VOIT) using the reflash box with firmware option. I have a new KHD-5L1 cable. When I inserted the DMS, the regular green flashing started. I left it for 15 mins or so, came back and both LEDs were off. I hit the reset button on the deck, and turned it on. CD Changer did not show as a source. Then I used PH DMS Tools to do a full repair on the DMS, and tried it with PMM. PMM recognized and initialized the DMS; PMM options verified KW 13.01 firmware. I then tried again in the car, no luck.
Other stuff: when I turn on the deck, the PB LEDs do come on. The red is constant, and the green comes on for a few seconds, then blinks every 5 seconds or so with a 1/2 second duration. If I turn off the deck, after a few seconds the LEDs turn off. So it seems some communication is happening. I also tried pulling the bat neg cable with everything hooked up. When I do that, the CD changer source is shown as an option on the deck. If I switch to it, it says Aux Ext on the screen. However, nothing happens, and the LEDs are not on on the PB. If I then hit the Kenwood reset button, the behavior reverts to that descibed previously (ie LEDs on PB come on and flash, but not recognized by deck).
I tried flashing firmware again (same version, etc) but no change
I pulled the cable and determined the connectivity with a multimeter - then compared with what's published in the WIKI, and all connections match, so very likely not the cable.
The DMS is a 160GB, and the box was hacked in June 2007.
At this point I can only guess that the deck is not compatible (although Kenwood Canada told me the new decks should work fine since the changer protocol has not changed), or that the deck is defective, or that the PB broke during the switch somehow. Another debug option is to reflash to VW firmware, and try my old stock VW deck to confirm the PB isn't dead.
Any help/advice would be much appreciated!
Thanks.
