Bluetooth adder to OEM deck - 02 Chevy 2500 HD

[ScottyBoy]

I used to have an AUX input module when I had my factory radio in the dash. It was not a Bluetooth, but it had two sets of RCA inputs. I had one set connected to a DVD player which I custom mounted where the stock cassette deck was, and the other set I had a headphone jack connected to it so I could listen to my iPod or phone. The module was a PAC AAIGM9 if I remember right.

Yeah I am familiar with Pac products and that is the one that basically piggy backs the stock tapedeck or cd changer. It would definitely do the job, but still, with the cables! I'm even going as far as to utilize the Qi charging system in the truck for the Galaxy S4.

Looks like Parrot makes a unit that will do phone calls and A2DP.

It's not exactly what you are looking for but I'm not sure anyone makes exactly what you are looking for.

So you want to keep the factory radio but have a well implemented, high quality Bluetooth connection that can be used for streaming audio but with no extra wires?

I think your only bet is to budge on the wires or the factory radio. Can easily add and aux in to the existing radio, probably even USB that will charge your phone or buy a new radio that has Bluetooth built in. If i was dead set on streaming through bluetooth I'd go with a new radio. Even if you somehow got the streaming working you'd have to do all the navigating on the phone itself, a modern aftermarket radio can control your phone.

Ok! This is interesting!! I do like the screen feature since I would have a void to fill with the removal of the stock tape deck. My original though was to possibly build in a Google Nexus 7 tablet for navigation, back up cam etc, but those would be mods after the bluetooth this is worked out. I will do some home work on this one. Thanks!!

Carlsbad huh, I'm originally from NM too. Born in Santa Fe and went to school at NMSU in Las Cruces.

Yes it would be nice to have the nice Navigation deck with back up cam etc put in and a new dash plate made to keep it looking somewhat stock. However I priced it out, and at $2,000 I'm not willing to dump that much into a system like that. Plus from 2001 and newer models, chimes, buzzers etc from the door and the message center run through the stereo and driver door speakers. To change the deck would require an additional module to control those things. On top of that, I have the time to tinker and learn something about bluetooth. For example, since i have been researching this I have learned that I can operate any electrical device in my home utilizing bluetooth. Everything from opening my garage door to turning on lights to starting the dishwasher. As long as I am in range of the receiver.

It is possible to achieve wireless everything, I'm finding out as I continue to research this project. At first I accepted that I would still need to have the power cord hooked up to my phone to keep it charged. Then I learned that with the Samsung Galaxy S4, utilized magnetic resonance charging capabilities, (Qi Standard) meaning that with the proper charging pad, and either special back cover (some of which obtain the same dimensions of the OEM back cover) or special battery that fits under the original back cover, simply laying the phone on the pad or even hovering within 1/4", the phone will charge. Awesome right, and the kit is only about $65-70 bucks. I can then work the charging pad into the center console or tray above the OEM tape deck.

Additionally, I am not exactly sure of the power output of the stock unit, and I am not 100% sure that may play into sound quality a bit, but if anything, only at higher volumes. However, the Samsung Galaxy S4 (2012 models and later) has implemented the aptx codec for streaming audio, which A2DP supports. As for bit-rate quality that converts to about 384kbit/s on 2 channel and 767kbit/s on 4 channels. Where as typical mp3's run at 320kbit/s I shouldn't lose in sound quality.

As for price of the project, This is what I am looking at so far in comparison to $2,000.

Bluetooth Set up:

Bluetooth Module v4.0 A2DP: under $20.
Various voltage regulators and capacitors: under $15
Misc parts: $5-10

Wireless Charging:

Qi charging kit: $65-70

No, you are wrong about needing modules to replace the radio. That didn't start until 2003. Some 2000+ cars need modules, and the Trailblazer started in 02, but the GMFS trucks didn't have the databus radios until 2003. So all you need is a basic $10 harness , a mounting kit, and an antenna adapter. $40-$50 in parts at the most is all that is needed to install an aftermarket unit. None of the turn signals, or warning chimes are affected by removing the radio on a 2002 or older truck.

As a matter of fact, I have several used Gm harnesses, and a 95-02 mounting kit as well. I might even have an antenna adapter I can send you too if you go that route. Just give me a few bucks for shipping and you can have it.

Well that's good to know. Thank you for that information! I am going to give the bt thing a try. With all the research I have been doing, and discovering new possibilities with bluetooth, I am interested to learn more. So if I doesn't work as I imagine, I will hit you up for that.

Thanks again.
