How to Add Bluetooth 4.0 to Any Car Stereo for 12$ ! Complete Guide !

D I S C L A I M E R :: horrible diction // super old video - SHIT HAS IMPROVED SINCE 2017

The only reason why I leave this up is that it SEEMS to have helped SOME, and the comment section seems to be a good place to exchange GENERIC radio modding intelligence.

In this video I’ll be documenting how I integrated the CSR8645 Bluetooth Module into a Blaupunkt Car Stereo. Purchase links below:

5v Bluetooth 4.2 & 5.0 Boards :
[12V variant not recommended as car voltage can go up to 14.5v, which the isolating DC-DC converters do not tolerate]

Silent MP3 File (80min, full audio CD):

Differential (Balanced) vs Single-Ended Audio Explanation :

DIN Connector Pinout:

Song:

BT Board DC-DC Regulator (useful for finding out what the rated input of your board is)

If you have any questions, feel free to ask down in the comments :)

nobody appreciates practical technical knowledge anymore nowadays. i liked it and nevermind the haters, this is craftsmanship.

[EfrainQuezada]

I didn't know this was possible. I live in compton, stealing stereos isn't as big of a pain as it was in the past but I don't want a shiny ass stereo unit in my old car. This is perfect.

"Time Waste" comments really ignore the knowledge acquired by you in this process. Though I'm not at all in this field I really enjoyed.

Great for factory radio if you don't want to replace it.

I had to take the time to say you did a quality job on that man very good work, you heat shrinked every wire, you didn’t hot glue the module in you took the time to drill holes and screw it in, you twisted the wires so they weren’t just floating wires, i seen some taped down to the board too! Very quality work man

the best feature about your Channel and your videos is that you answer people's comments that's very important thank

[HacksawJimThuggin]

Above my head, but I appreciate the work and initiative.

A few years ago I wanted to replace my e46's stock radio-TAPE but I was suposed to buy a "Standard Radio Frame" from $$$ BMW $$$...
In the end, I converted the original to a Radio-Tape-BL (3 function) while the BOM was even cheaper:
5$ for the (cheapest I could find back then) bluetooth speaker to dismantle
0.5$ 1x 7805
~0$ : 1x 1N4148 + 2x 33Ko
I'm using it on a daily basis so it worth every second, Waste of Time my a$$.

People who disliked this video clearly rather waste their money on buying new unit or not skilled enough to complete this mod.
Great video and I'm gonna sign my unit up for this. Cheers!

You don’t always need to reprogram. I added the wires to my generic oem head unit and when a device was plugged in, the option was added to the menu.

A 55Ah battery drained with 50mA is empty after 46 days, not 114 years. And you shouldn't completely drain a car battery anyway. So let's say we can safely take out 30Ah, and the car electrical system also drains 50mA, then we're already down to 12, 5 days, less than two weeks...

Nice skills
The soldering, the knowledge and the explanation is really amazing

[jamesstone]

This is best for a car where the hvac is built into the radio making it impossible to replace the radio. I.E. i did something similar in my 2008 Lexus is250. This car is just old enough to not have Bluetooth. It worked great, but if you don't know what is what you'll have to read a lot. I have some experience so it was easy for me to do.

This is a great video. It may be a lot of work but this is a great mod if you live in an area where aftermarket radios are stolen. Even if an aftermarket is cheap crooks will still steal it and sell it.

[fatonics]

I did it in few car audios, soldering is my passion i do it for 15 years and im only 30 years old 😎 thats passion keep it ❤️ great job

[peten]

Great work. My stupid porsche radio does not have bluetooth. It will cost me 600 to purchase a bluetooth. I am going to try this out.

[vanepico]

In my opinion these older more OEM stereos are much better, they don't blind you at night! I had the aux version of this stereo but it went in a car I scrapped :(

[dismanca]

Brilliant low cost solution for someone with the knowledge and skill or even someone who likes to tinker.

[TTRVision]

nice soldering iron, one of the best on the market and one of the last quality products 100% made in Romania. I think this model is from 1970 and still rocks on!
