hey guys welcome back to the channel so today we ran into a little problem on the is-250
this is a problem that i thought i could avoid on this car since it spends most of his time inside
garage kept and not much time in the sun but the navigation screen stopped reacting to touch this
is a very common problem on the navigation screen for the 2is so what i got today is this 15 or 20
digitizer i bought on ebay we're gonna go ahead and take this thing apart
and replace the screen in front of the screen that reacts to your touches
it's a pretty easy install as long as you know how to take off the radio and
take it apart and swap this thing out with a little ribbon cable on it so stay tuned
so we're inside the house now what i'm going to do just to make this a little bit easier to work
with i'm going to take apart the brackets for this whole thing and then separate the radio from the
navigation unit that way i can work on the navigation unit by itself to make
it a little bit easier because this thing is pretty freaking heavy and it's hard to
kind of just move around and get these plastic things to pop out out of the way so we're just
gonna go ahead and just separate the radio from the nav screen right now
this piece comes off with a tpms computer on top of it
these things are pretty sharp so just careful with them so you don't cut yourself or damage
anything so now that we got it apart uh separating the nav screen should be pretty easy i think
you just kind of lift it apart and it slides into the radio a little bit it doesn't just like fall
right apart be careful not to break anything i haven't done this in years so i don't remember
the radio definitely slides back but
it's got this
ah there you go okay that sounded worse than it was so if you look under here there's actually
two little tabs right here that go in and then there's another center right here
did take a little bit of skin off my finger but oh well
yeah on this side there's a these two little hooks that
hold it on that's what was holding it on right here these two little hooks right here in the
tab so didn't damage or break anything but it is kind of scary when it pops out so what i'm
gonna do now is i'm gonna just take apart the four screws that hold the face of this i'm gonna try
to slide this the face off of here like i said i haven't taken this thing apart in freaking
11 years so i don't remember exactly what to do but i'm just guessing at this point
uh
this pops off just i'm just going to go ahead and unplug the ribbon cable here so i don't damage
anything the ribbon with that little plug you can just pull it straight out from there so this is
the screen we'll put that off this side
so now what we have to do is get inside here and change the digitizer
so it looks like i see two screws on this side and then two on this side that
give us access to the metal plate to take this off so go get some smaller screwdrivers
sure what this is but it's gonna be in the way of the bluetooth it's a little bluetooth module there
go ahead and unscrew these
bluetooth module back and then this thing comes off pretty easily maybe i'll take
apart these two rails right here that kind of keep the screen at that angle
actually that those two still have two more screws back here that hold it
so got all those screws out let's see if so yeah this thing
moves a little bit better now a lot of ribbon cables back here
let's okay ahead and put this another angle that we can work on it
all right so slide that cover off now we have access to the digitizer screen so just
first thing i'm going to do will actually just pop this ribbon cable off back here
usually just flip the thing up slide the
slide the cable out and then unplug this other little supply wire right here
just pop it out with a little flat head so we got this out so we're gonna
put everything aside work on this little screen
so now that we got this thing apart first thing i want to do is so this thing kind of
separates from there but you just got to be careful that there aren't any other ribbons
or anything that might damage because it just plugs and just plugs right into the back side
here but it's covered up right now so the board is actually mounted to the back cover and then
this guy's mounted to here you can get a flat head in there and kind of pop that out you kind
of reach in there and you also use the holes back here you get a smaller flat head in there
pop that out slide this thing right out so that's the digitizer
i think it's glued might be glued down get the new one out and see so it is
pretty thick glass it's got its own tape on it so this sides looks like it's taped down too
i'm gonna put some of these screws back in just to hold this down for now because it wants to pop out
yeah if i get a razor blade and just cut the glue out so i
got a little razor blade just we'll go ahead and just cut this off
so i got this baby removed so you can see right here there's like a little bit of residue from
the glue or the tape left i'm about to clean that off around the basil and then back here you can
see this is the old one that i just took out so i'm not sure what really goes wrong with these
digitizers i know they just they everybody that has a nav unit ends up going bad at one point
or another into its life i did take it off pretty cleanly there was some areas where the glass kind
of cracked when i got the razor blade underneath but that's fine i'm just tossing that in the trash
anyway and then the new one came with plastic on both sides so just peel that off make sure
everything is nice and clean maybe do a wipe down with some alcohol just to make sure you don't get
any fingerprints or dust in here all you do is just peel the tape off and then put it back onto
here once it's all cleaned up and you should be good so i was able to scrape most of this off with
my fingernail and then just using a card to scrape most of the adhesive off but it's gonna leave this
film behind so what i did is i put a little bit of acetone onto a cotton ball and i just basically
just wiped the edge very close don't get on the screen because acetone melts plastic and you can
see it's taking off the paint on here a little bit of the paint but this is the only thing
that's going to really take off all this adhesive really fast you could try brake parts cleaner just
little break parts cleaner on a little cotton ball too but that stuff evaporates really fast
that probably won't take off the paint but this definitely takes off the paint but it does loosen
the adhesive a little bit so you can actually scrape it and clean it better than without it
so now that i got it pretty much cleaned up with the acetone i want to take one of these
alcohol wipes i got a bunch of these from screen protectors for iphones and stuff i'm going to just
wipe it down and i'm going to use that little dust sticker that these things come with and then get
all the dust and crap off the screen before i put the new digitizer on just want to clean off
the screen from anything that we're working on a little bit of adhesive and things that got stuck
then clean off the all around the edges leftover residue and anything from the asp
that the acetone didn't get off along with all the little cotton ball hairs
and lint take one of these stickers and just get the lint and everything off of here
so now that we got it pretty much cleaned up then got more lint on here
i'm gonna go ahead and get the screen on here
yeah this thing just attracts went like crazy
all right so we want to get this off peel the protective layer
and then get the tape so yes yeah just peel it just make sure you
get all the way down to the actual adhesive itself and not the top layer of
the make sure you have the thing on the right orientation so i made sure that the
little ribbon plug is right there now i'm just going to lay it down on one start on one corner
make sure you're square once you confirm that your your square on all ends
go ahead and put it down
and just go ahead and just go around use your
make sure it's all good go ahead and peel the protective layer get this guy back on make sure
get the cover back on get the ribbon over
so we'll go ahead and plug this thing in you slide it into the little slot and then
make sure it's firmly placed it's only got four contacts so it's a pretty big ribbon
and then just get your screwdriver and then just press it down the retaining clip
we'll go ahead and install it back into the unit and then we're going to go test it out in the car
so we're in the car now i plugged up what i could on the back here just to get it turned on i didn't
have the face on it at first and it wouldn't work nothing would respond so i had to go grab the face
put it in here and just plug it up right now and looks like everything is working as far as the
the screen goes which was what i was really testing right now so let me see so yeah like
telephone works telephones connected works so let's see
yeah i mean i was just making sure the digitizer worked but it looks like all my buttons work now
beep off be language
so all the spots work on the digitizer so we're good with this so i'm gonna go ahead and put it
all back together and reinstall everything hey guys thanks for tuning in all the way
to the end of this episode on fixing that digitizer on the nav screen i know this is
a very common problem and if you're watching this video you probably have that same issue
as you can see it's a pretty straightforward install as long as you know how to take everything
out of the car without really damaging too much of your dash or anything else
even when you take it out and get everything off you know you gotta just be careful not to
damage anything but anyways if you found this video useful give it a thumbs up if you haven't

gonna go ahead and just change those leds out so on the next episode i'll have a quick diy
