This can work but if you want maximum performance for your GPS system
in all conditions, you want antenna outside where it is not ever
shaded but any part of car as it trys to track the satiltes in orbit
under varing conditions. The whole beauty of the external antenna
setup it that it lets you do this. When you get in marginal coondition
like in forests, deep valleys and in heavy precipitation you want
maxium possible gain and reception field for your antenna.
The answer to your question is yes, ONLY if you are willing to undertake
some modification work. GM is a DIN and a half size for decks. Your best
bet would be to get one that is a DIN with a motorized face (screen).
Installing one is very simple and the tuner pack for your GPS function is a
separate piece that will mount udder your seat or else where similarly easy
to access and mount. Running the wires in a simple chore to do also,
including the GPS antenna, it is not harder to run then an antenna for a Sat
radio set up.
Are you on some space cadet trip or something? I am not at yours
anyone elses "call". I do not stay in threads when trolls and
children (such as yourself) come out to play.
Apparently you are not here to help anyone either because as usual you
ignored the OP's question and went off on your own tangent again. FYI trust
me, if I were in need of assistance, you would NEVER be the one I call!
Since you don't stay in threads where you feel there are trolls, maybe you
should stop posting all together!
Troy, something that I want to make sure you are aware of as this is ALWAYS
a shock to people. With yours being an 02 you will need a special wire
harness adaptor, and if you have the Bose and or On-star this will also
effect the harness you need. If you have a non Bose or On-star you will
need to use the GM-RC01 harness which will drop you about 100 bucks. You
CAN NOT install an aftermarket radio in a GM product that requires this if
you do not use it. The ones for Bose and On-star cost more.
The dash kit you will need is the 99-4000 from Metra and you will also need
and GM mini to standard antenna adaptor.
thank youo for your help. i have a few questions.
i do have on-star, can you guide as to which wiring harness i will need? is
99-4000 for double din units? if it is not, can anyone direct me to some
guides, or explanation, as to the modifications needed to fit a double din
Thank you again for everyones help
I'll have to look up the harness you need, give me a day and i will get that
for you. As for the kit, there is no such thing as a double din for a GM
truck. If you want to install a double din, you will have to make your own,
this will mean some fiberglass and/or abs working, cutting of your dash trim
bezel as well as cutting of the dash above the radio opening and down by the
This answer the questions?
Yes, unfortunately you will still have to use a harness as there are no
other harness adaptors that would replace it. However, you can actually get
away with the OS-1 vice the OS-2 which will save you some money. The -1 as
I recall would run about 80 bucks. Difference between the two, are
functions required for certain GM cars, they both work on the 02 trucks and
As I recall, you will be a half din shy on space on the inner dash if you do
not cut some of it out. One problem that you will dun into if you are going
to try the 2 din unit is that you will (on top of everything else) have to
make your own mount brackets as there will be no (easy) way to mount it into
When you pull your dash trim bezel off, you will see one of two ways your
factor unit mounted, either slide locks (1 on ea side) or three 7mm bolts.
If you have the bolts, making something out of cheese strap is easy, if you
have the slides, you will have to either break them off the factory deck or
buy the 99-4000 kit just to get them, then device a way to mount them and
all that fun stuff.
Though it is your vehicle, unless you bought it already, you really are
better off with a single din motorized screen unit, looking at it from the
ease of installation aspect of it all.
thank you for the advise. i plan on buying a spare dash bezel, to do this
project. i am really set on a double din unit, i like the idea and look
better than a single din. i wish they manufactured a din 1/2.
thanks again. thanks for the advise on the onstar issue also.
Good luck and take your time doing it. I have so many things like this that
come out jacked up because people get into a hurry. Make sure you get it to
fit properly in the dash before you start to cut up the bezel. Don't for
get to let the deck stick out the bezel about a 1/4" to 3/8" to allow for
the face (motorized I assume) movement.
If you don't mind me asking what brand equipment are you going with?
i am looking at either the pioneer AVIC-N2 or the kenwood P-NAV6019 DDX6019.
i am looking more toward the kenwood, 1 i already have the sirius receiver
for it, and its bluetooth compatible, the pioneer is not. im glad you wrote
back, do you by chance know the measurement on a typical double din unit?
do you have a recommendation of equipment to use. i like the pioneer for
the VDD (but no bluetooth). i want the bluetooth, so that i dont have to
use onstar. i can use my phone and have GPS and communication in one unit,
without a monthly fee.
were u the one that told me about the chimes harness to get so my chimes
would still work? i was reading a post from someone (another forum) who had
a trailblazer, and had to install both the pioneer unit, and his factory
unit, to make everything work. will i have to do this if i use the wiring
harnesses, you mentioned?
thanks again for all your help.
do you have a recommendation for forming ABS panels? i dont care to use
