hi, new here!!! been doing a lot of reading in here and i think i am reading correctly,
i am putting anaftermarket radio in my 2005 cobalt base model sedan. i got the harness on ebay, the power wire is separate and will need to go to the fuse box i assume, will this install affect any other function of my car? and i sure hope the harness works. can post a pic later, seems to be a generic version. no brand name that i can see, i hope i have another place on the fuse box, already have taken two fuse taps with the cd changer i installed after i first bought the car. thanks

 

move the cd changer wires to the remote off the cd player and use that to the ACC wire for the new cd player

 

i know i just installed a aftermarket radio in my 2007 and i need to buy a gm interface so that all my alerts work for the car.. i dont know if it applys for ur 2005

 

nah 05 is diffrent

 

so, i should not lose any car functions in the 05 cobalt by removing the factory stereo? that's is what i am picking up on in this forum correct? thanks in advance!!

 

i wish i could tell you but in my 07 i did

 

yes 05-06 has no adverse effects. try it pull the radio out and ride empty for a while. nothing will be different except the lack of tunes. 07+ different story

 

thank you, i think i have my weekend project!!!

 

Well, it is done!!! it went OK, i had to use a Scosche Dash kit instead if the American Intl one i wanted to, the one i wanted to use put the stereo back too far and did not leave room for the wires to plug in. I installed a Sony HU with USB port, i am removing the 12 disc changer i installed 3 years ago, since my tunes will fit on a flash drive! (take half the car apart AGAIN to remove the CD changer) Anyway it was well worth it, the sound it so much clearer with this radio, i also installed a pair of surface mount tweeters in the rear of the car. That alone even with the factory radio made a BIG difference. I will post a pic soon. My only complaint is i cannot locate a fuse to tap in the fuse box that will work with the ACCY position of the key. My car is a base model and most unused fuse slots do not even have a circuit behind them, just empty plastic holes! So the stereo only works with the car on.

here are some pics

 

use the wiper or sunroof fuses... youll retain RAPP too

 

i did use the wiper fuse, it still only works when the car is on, not on accy, but it is really not a big deal, what is the RAPP ?

 

RAP is Reserve Accessory Power (i think thats the wording). It allows power to the windows and radio after the car is shut off but when you open the drivers door is cuts the power off.

 

correct on most vehicles the wiper and sunroof retain the rap but on some ls/lt models they dont for some odd reason. you can test and find a different one if you'd like said feature
