I bought my first Phatbox on Ebay, it is a kenwood music keg with 20Mb DMS. I've never had it working and have had trouble getting it going on my Audi (Symphony I)
In virtually all trials to try to get the DMS to load the Audi firmware, the following happens.
After each update/repair of DMS, the first bootup of my Phatbox seems to start okay. (red light, then flashing green light for 2-3 minutes (never as long as 7 minutes))
In some trials, the green light flashes quickly, other times more slowly (2 per sec).
After the phatbox lights go off, switching the head unit on and off has no effect. The Symphony Radio shows "CD Load" but does nothing.
Unplugging the phatbox and replugging it has little effect, the red light comes on for 15 secs then all lights turn off, and I hear a slight click, like an off switch.
The only way to get it to do anything after that is to go back and reload firmware into the DMS (see below) and give another try.
First tried Kenwood Music manager software on my Vista machine. I could not get any headunits to appear in the Headunit update window. Then I downloaded (non-kenwood) Phatnoise music manager and this time got headunits to appear, Updated firmware with version 7.02 for Audi Headunits. (all subsequent tries have been with this firmware.)
Installed PhatHack DMS Tools and tried various times with "Install non-hacked firmware" both checked and unchecked. Tried partial and full DMS repair on the vista machine, and it never seemed to complete properly.
I've now moved both the Kenwood Media Manager and Phathack DMS tools onto my wife's XP machine, in case Vista was the problem.
I've tried combinations of so many different things, which include
Copying 7.02 Audi firmware from phathack site, directly to PHTSYS
Phathack DMS Tools Full Disc Repair - various trials non-hacked box checked and unchecked
DMS Doctor shows System Files Failed
I'm a bit worried, that I should not have been using Phathack, before at least getting the DMS to work. If I inadvertently hacked the phatbox without first getting the DMS to work, does this ruin the box?
Any advice will be appreciated!
