Who makes a good after market radio that fills up the space rather then using a kit to make up the difference of the space? My CD player stopped working and Gm wants $200 for a new radio that will probably not last long, some of the back lights are going out, blah.
Your average cost for a double din made with any average reliability will run around $150+.
By the time you add in the necessary appurtenances you'll be similar cost. $30-$50 for a solid dash kit. $80 for a wire harness ($40 online). $15 antenna adapter. That will be your basic double DIN. Same cost and parts for a single DIN.
I can't speak to the cost and/or reliability of a cheaper brand/product. My HU cost estimates would be something like a basic Sony, Alpine, Kenwood.....etc.
There are for sure sub $100 units but I suppose it will depend on the features you're looking for.
Like I said, the above appurtenances are the same no matter which unit you purchase....it's up to you then to find the HU that suits your needs.
This is the route I went - my 2007 Colorado only came with an AM/FM radio and the knobs didn't even work right.
You can shop around on Amazon for a better price on stuff but I chose Crutchfields for ease of ordering :)
Installation took about half an hour taking my time no hurry.
I have to agree regarding Crutchfield. I've used them for more years than I care to list and have never had a bad experience with them. Their support techs are also great. Extremely knowledgeable and patient.
I recently replaced my stock radio in my 2008 Canyon with Pioneer model (AVH-X2700BS) from Crutchfield. Very simple install and perfect options for my needs.
I will reinforce that Crutchfield is the best place for car stereos without a doubt. I went the single DIN route. I paid $137.46 shipped for a Sony MEX-N5100BT, antenna adapter, radio adapter, the wiring interface (bells and chimes), and the dash kit (the filler for the other space under the radio). I personally went for a single DIN so that I could have that extra space under the radio, but I'm also in a single cab work truck with almost zero storage.
Plenty of support here already for Crutchfield, but they get my 2 cents as well. Now that I'm beyond support on most of my projects I don't buy from them much anymore, but even when I've been trying to find an interesting situation (antenna adapter from a Chevy HHR antenna to a GM factory stereo in a S10) they were beyond helpful and got me the right thing - even though they sent me the wrong one first, on an order JUST for an antenna adapter they sent me the correct one for free.
When it comes to stereos I've had the best luck with Sony, although if you ever want to go with Sony amps I highly recommend sticking with a Sony HU. Their preout voltages run a little differently...
