What do i need to install a aftermarket radio in a 2002 silverado 1500 hd crew cab?

Question

i want to replace the radio in it and i need to know do i need a bypass module for it to get power and will it affect any security features i know i need a wire harness, radio dash kit and a antennae adapter, and does any one know how to remove the speakers in the doors.

Answer 1

Not really a bypass module, that is more for alarms, but there is a large CanBus that you need to buy, which usually arn't cheap.  BestBuy and Circuit City usually sell them for about $140-$120, but I believe you can still get them from WalMart for about $80. Just let them know you have an 02 Chevy, and they'll know what you are looking for.  Should say "For 01-03 GMC Vehicles Without OnStar".  As far as the install kit and antenna adaptor, those are both standard GM.  The dash kit will be a 95+ GM Multi Kit, and the antenna will be the GM Antenna Adaptor, both should run anywhere from $10-$20 at most stores.

In case you are wondering whether you can not use the CanBus and just wire it in yourself, you can, but it is not legal, and there are some safety features in your vehicle that will no longer function :-\

I'm assuming for a 02 you don't have OnStar, but if you would like to keep your steering wheel controls, there is a seperate kit you will need.  The steering wheel control module will actually depend on the stereo that is being put in there, but you can check the peripherals website to find the module you will need for your stereo.  I will warn you though, steering wheel control mods are not for the faint of heart.  If you havn't worked with 12v electronics before, I would recommend taking it to a shop to have the work done, because I have seen SOOOOO many people blow their airbags because they forgot to disable SRS before they started in on the job.

**A canbus is basicly a small part of a larger computer network built into your car (lamin's terms), instead of having full ECUs built in to each component in your car, they build in CanBus modules which run off a central ECU, (or several different ECUs depending on the car).  The CanBus comunicates with the ECU, in the case of the stereo, to give you warning charms regarding various vehicle sensors, vehicle speed for road noise concellation, and other features.

Answer 2

You won't need a bypass module for power, power is simply power. However, to further assist you I'm going to need more information on your vehicle. Do you have OnStar? Steering Wheel controls? Do you want to retain the door chimes and informational warning beeps?  

Answer 3

you need this, if there is RDS on the radio display
