Blaupunkt Models

[Andree Vandestreek]

Foundedin 1924 in Berlin as "Ideal,"[4] the company was acquired by Robert Bosch AG in 1933.[5] In 1938 it changed its name to "Blaupunkt", German for "blue point" or "blue dot", after the blue dot painted onto its headphones that had passed quality control.

Blaupunkt took over a former Philips/Grundig factory in Portugal to produce automotive head units. It is still owned and operated by Bosch, used exclusively to make OEM units for car manufacturers and 24V (e.g., Coach) AV equipment. Later, factories were set up in Tunisia (speakers) and Malaysia (speakers and electronics).

In 1949, Blaupunkt advertised the first FM-capable car radio.[6] By the 1960 and 1970s, Blaupunkt had become one of the leading German manufacturers of car radios and car audio equipment. In 1983, it began selling an in-dash CD player.[6]

Blaupunkt was involved in developing the Autofahrer-Rundfunk-Informationssystem traffic-information system for car radios and provided this feature on their German-market car radios from the late 1970s. The company attempted to have ARI used in the United States but had only a few radio stations per major city involved.[citation needed]

For many years, Blaupunkt car audio equipment models often carried the name of a city somewhere in the world, e.g., "London RDM126". In Blaupunkt model terminology, this can be translated as "An RDS CD player capable of controlling a Multichanger, rated at 430 W RMS (4 30 = 120) from the model year 1996". High-end models typically had German place names.[citation needed]

Blaupunkt also used the brand "Velocity" to sell products aimed at the top, audiophile end of the market. Audi, Volkswagen, Porsche, Mercedes-Benz, Proton, Vauxhall, Pontiac, Holden and BMW all fit Blaupunkt (now simply Bosch) products into their cars, often branded with the car manufacturer's mark (e.g., The VW Gamma, Audi Symphony or BMW Business CD lines), with Fiat using them, occasionally unbranded but generally unmodified. Some later Holden Astra models are fitted with Blaupunkt systems (with others being produced by Delphi Automotive). Blaupunkt also specialised in coach installations, selling TVs, multiple-speaker setups, and PA equipment to that industry. That part of the business has remained with Robert Bosch Car Multimedia GmbH, a 100% subsidiary of Robert Bosch GmbH. The Blaupunkt branding is no longer used, even on 'hidden' stickers.

On 12 July 2012, Blaupunkt signed an agreement with Rockford Fosgate granting the Rockford Corporation exclusive distribution rights for the company's car multimedia and headphones range for the North American market. Rockford Fosgate sold Blaupunkt products, including car radios, navigation, amplifiers, loudspeakers, rear seat entertainment, connectivity, and electronics for the OEM market through distributors.[7][8]

I'm really hoping somebody could help me with some pointers on using the arduino to interface with another device. My car stereo has an un-used cd changer port. I'm trying to open the audio input, but first I need to fool the stereo by emulating the cd changer. I'm hoping the arduino can do this.

My biggest weakness is in the software. The stereo has a data-in and data-out pins (no clock). I've found nothing online to describe what protocal is used - maybe it's something like rs232, but I'm not sure. Someone mentioned it's 2 wire (rx/tx) async. serial protocol with 9 bits of data where the 8th bit is used for synchronisation - but I'm not certain...

Could someone suggest any pointers on where to start? How to test what kind of commands to send to open the audio in? Would you know where I could find some examples of simple programs that might be able to help me figure out how it communicates?

I suggest you try to find more information on the protocol by searching google or some of the in-car audio sites. Use the manufacturer and model name of the radio unit and terms like protocol to see what you can come up with.

I'm trying to connect my MP3 player to the aux input of the stereo. From all the googling I've done, it seems this auxillary audio port will not open unless it gets the right command from the cd changer that should be connected to it.

I tried shorting the tx and rx pins, which apparently worked on older models, but doesn't with my version of firware.

I took the stereo out to try and bench test it, but I couldn't even get passed the security settings. Seems it needs to be connected to the cars computer to function... and seeing as it's feburary I'll be waiting until the weather warms up before I sit in the car with my laptop...

how is it going your research on blaupunkt protocol?

i'am interested on the same thing, i already tried to sniff my blaupunkt headunit, got some responses but dont know the exact protocol to estabilish communication like a cd changer.

I haven't touched this project for some weeks now, so I'm no further along since my last post. I think it will be some weeks before I have a chance to look into this again. But if I do find anything I will be sure to share it with you, as I'm sure I will need help with it!

This protocol uses at startup 4800 baud, 9 bits, 1 stopbit. It can be 'directly'conneced to a PC serial port, though the RX/TX levels of the radio are at TTL 5V (but inverted to be compatible with RS232C of a PC).

please tell me what kind blaupunkt model do you have?

i have a blaupunkt fiat 199 head unit, already sniffed the tx/rx line. every time i turn on head unit, i get the stream "E0 06 80" (sniff at 9600 baud, 8 bits).

IF there's anyone who's finding about the same results as I do I'd be very interested in dumps or more specific info about commands. You could have that if you have a CDC because you can then send it commands by using the HU's buttons and such..

RudolfC, i have been playing with my car headunit and so far i have been using your information. The codes seems to communicate with car radio. On last code 0x180, 0x021, 0x14F, i can only get on my headunit a text "CD CHANGER", but still no audio input accepted by headunit.

i believe few people still interested on blaupunkt protocol, but if anyone have more information about this, please reply. The information collected so far is enought to build a simple cd changer emulator, but im sure there is more commands to be interpreted.

already tried to reply command 0x0a7, but i didnt get any conclusion yet. i think radio is waiting for some text information, like "CD ERROR" or "NO CD". but i dont bet my fate that it is possible to write text to radio.

Just last week, we had the French brand Thomson announced the launch of 3 models of QLED Google TVs from its stable in India. And today, the German brand Blaupunkt said that it is unveiling its 3 models of QLED Google TV. Both Thomson and Blaupunkt's new models are in the same 50-inch, 55-inch, and the 65-inch categories. it cannot be a coincidence that the contract manufacturer SPPL (Super Plastronics Pvt Ltd) is the exclusive brand licensee for both Thomson and Blaupunkt in India.

Like in the case of Thomson, Blaupunkt's new series of QLED Google TVs would be available during the upcoming Flipkart Big Billion Days (BBD) festive sale. The dates for the shopping extravaganza are yet to be announced.

It is not known whether the Thomson and Blaupunkt's 3 models carry similar features. But the German brands' 3 TVs have been priced higher than Thomson's. The Blaupunkt's TVs will be available in 50-inch for Rs 36,999, 55-inch for Rs 44,999, and 65-inch for Rs 62,999. These are Flipkart festival offer prices. The TVs also enjoy 5% cashback offer if bought on Flipkart Axis Bank Card. There are also some bitcoin and Byjus online tuitions thrown in as special freebies along with the purchase. The TVs would cost more once the offer period ends.

In terms of features, Blaupunkt's new QLED Google TVs come with 60W speakers with Dolby Atmos support, Far Field Voice Control with Google Assistant, and provides 360-degree surround sound for a theatre-like experience at home.
