making this video is a follow-up video
to my original of how to unlock these GM
class 2 RDS radios found in most
vehicles after the year 2000 your radio
looks like this and you have one of
those now in the other video I
demonstrate how to remove chips from the
board and I demonstrate the location of
the chips etc etc now I have found with
some further research there is a version
of this radio that if you remove the
chip from the board you brick the radio
you Bay you basically make your radio a
paperweight I don't want people to make
their radio a paperweight because I
don't want them to come storming down my
front door with torches and pitchforks
so I'm making this video as a follow up
as a cautionary follow up of which radio
not to do this too now as you can see
looks like any of the other RDS radios
this is a cassette CD combo this came
out of a 2002 Chevy Trailblazer I think
nothing to it now here's the board looks
very similar to the other one but I
believe this to be the first version
everything on this board looks slightly
older than the other two in my previous
video now the chips you remove any other
ends in the other video or back here
now pull the sweater as you can see the
two chips in this radio aren't in line
with each other this is the security
chip in this radio right here as you can
see I damaged it
I had actually originally tried to
remove this chip and I didn't get very
far so I ended up
I tried pin eight which is back here on
this side it bricked the radio so I
recited the chip I'm not sure what this
chip is but this is these are the two
chips in the version it's okay to do
this too when you remove that chip that
it will unlock the radio the chips are
side by side see my other video for what
that looks like but if the chips are
like this and they're opposite of each
other ones vertical and once horizontal
do not remove the chip if you have this
version and you pull this chip off
you're going to ruin your radio and
you're going to be all mad at me and
everybody's gonna be unhappy I don't
know why this is just the rate that this
is radio must be programmed differently
internally it just these just don't
accept it
they don't accept this chip being pulled
off and they don't accept pin eight
being lifted I like I said I think it's
an older version the board looks quite a
bit older than the newer versions before
you try this modification make sure your
chips are both vertical if you have the
horizontal chip and the vertical chip in
this position don't just don't
so the board looks like I took the
liberty of removing the tape player out
of this radio just to make life easier
again there's the face of the radio
looks just like the other ones they all
look pretty much the same but
electronically they're different now
the other version which is also
extremely common this one these also
need the on signal from the class to bus
in the vehicle this radio is found in
cheaper vehicles like Cavaliers the
full-size trucks s10 s later Model S
tens this is the base model radio this
radio also has a security chip and it
doesn't have normal theft luck I don't
think but it still needs that quote
unquote on signal from the car's
computer I already remove the chip from
this one and it bricked it this radio is
no good I will show you right now here's
the plug it's just a custom adapter it's
an aftermarket adapter that lets me use
the older style GM plugs which my power
supply and everything is wired to and
that it adapts to the RDF style plug so
I can switch between the versions
without having to have several harnesses
laying around
if I put in the right way and that's it
the radio does nothing else it just
stays on error and that's it the the
ones with the fancier display and the
RDS and everything those are the same
thing they'll just say error and they
won't do anything else that they'll
still have a clock generally but they'll
say error the radio won't work nothing
happens now this radio I just got it at
a thrift store locally it was only fifty
cents so I didn't feel bad breaking it I
ended up using its CD player in another
radio that had a obviously broken player
module I'm going to take this faceplate
off because in such nice shape and
usually these buttons here I'll just
completely wore off the faceplate is
still good and it will interchange with
any of the other radios and I'm just
going to put this on ebay so if somebody
has wore out buttons they can fix the
radio the rest of it I'm actually just
going to throw away since it's garbage
now I'll demonstrate the other radio
what it does it isn't brick that was
intentional
it's hard to do this from behind a
camera no life and the blinking red
light now to turn these on this works on
all of them you press five seek forward
and the power button and it comes to
life
as you can see the security light stays
on you can do this for 10 minutes it'll
work 10 minutes at a time and you can do
this turning it on and off 10 times then
you have to take the power away from it
and reset it I demonstrate that in my
other video as you can see it works fine
but the only way you can really make
these work again if you switch them
between your vehicle is you have to take
it to the dealer for activation there
doesn't seem to be a workaround for this
particular style board
there's no 12 volt on signal now I power
these with a 12 volt on signal some do
some don't
this version period won't work the newer
versions after 2004 like the mp3 model
found in the Colorado's the ones that
the newer ones they have a slightly
different looking button they're a
little bit more modern I don't have the
one here to demonstrate it that one
needs the on signal it won't work with a
12 volt ignition signal but a lot of
these have that built in but just
disabled so that that's what that's what
that's how I can usually make these work
so I can just run them off basic wires
on my bench there's nothing special to
it nothing there's nothing funny about
this is just bare wiring right to the
radio everything's all nice and taped up
through my adapter RadioShack power
supply and Philips speaker the adapter
lets me plug these in as well without
having to have specific adapters or
multiple adapters I just have one plug
one plug type and that's all I use
just to recap just to make sure the just
to make sure and completely clear on
this 110 percent clear for everybody if
your chips look just like this vertical
horizontal do not try to remove the chip
you will ruin your radio that's the end
of it
the radios garbage you may as well just
throw it away if your chips are if you
have two chips in line exactly like this
one here
and there'll be one here they're both
and they're both vertical with each
other from looking at the back of the
radio forward you can remove the front
most chip I will even show it show it in
automobile radio since I have it handy
the Oldsmobile version different
faceplate same electronics I've already
removed the chip from this one because
it isn't one of the Oldsmobile radios
that will work without the signal we on
signal from the canvas the chip was
there as you can see there's a chip here
and they are both in line with each
other
this this is the style radio it is okay
for to do too I will put a link in this
video to my previous video and that will
demonstrate how to remove the chip and
what the radio does once it's unlocked
this video is just so people don't break
their radio and get all mad at me
