Guys:
The system 10 and other Toyota double din head units all suffered from a common
flaw in the past. Toyota cheaped out on the capacitors used in the deck, the caps
went bad slowly, and things like left channel playing softer than right channel
or CD playing softer than tuner started to occur. The fix is not tough, nor does
it have to be expensive. However, if you've never worked with electronics before,
make sure you find an A/V repair place that can do it. The parts cost a matter of
a few bucks, the labor shouldn't be more than $25 or $35. And FWIW, the System 10,
when working right sounds pretty good. It certainly sounds better than spending
$300 on a headunit you don't need. Especially when for $300 you could buy a new
Aussie Dp....but that's another story.

Perform this at your own risk. You need to get the entire head unit out of
the dash and CAREFULLY open up the CD player. You'll have to take the
entire contents out of the metal shell because the circuit board is on the
bottom. CAREFULLY (there are lots of delicate wires to pop off) remove the
circuit board from the unit - you'll need to unplug several plugs (look at
the way they separate so you'll know how they're supposed to go back on)
and unscrew a heat dissipator at the back right corner (be sure there's
enough thermal compound the back of that dissipator).
The capacitors in question are in a loose group at the back left of the
board. They are red 4.7 mF, 25v capacitors about 3/16 inch in length,
maybe 1/8 in diameter, and there are six of them. It is safe (as I'm sure
the electricity-savvy know - I didn't) to use a larger voltage capacitor (I
used 50v), as long as you can make all six of them fit. I would bother
asking for them at Radio Shack - try a more industrial-type electronics
store, like Shields.
That's about it. Put the thing back together, reinstall it, cross your
fingers, and turn the key. Your CD player should sound like new.
