Hey , i just connected a bluetooth module to my oem skoda symphony radio in the cd changer plug in the back of the radio. The bluetooth module is working bcs i can connect to it and it has this little blue led that is flickering. When i try to change to "cd changer" the radio doesnt see that i have connected anything to it . So it says "no cd changer" or smth like that .

Its an blth module from aliexpress just so you guys know.

I searched on google and it says that thats the right plug where i pluged my bluetooth module.

What can i do to my radio to see that i have my bluetooth module in the external cd changer

Here is the module link:I just found this on AliExpress:

RON47.60 | Car bluetooth Wireless Microphone Adapter Stereo AUX IN Music For VW Golf MK4 for Audi A3 A4 A6 8PIN for Skoda Octavia

Any tips are helpfull . Thankss

While this is connected to the CD changer plug, I don't think these use the CD changer option. It should be using the AUX settings? However, I could be wrong...

Either way, make sure you connect the red wire to 12V+, the black wire to 12V-. Then try the CD changer (as I guess it's meant to mimic a connection) and, also try the AUX option too.

My cd player doesnt have aux option but , BUT i saw on a forum some months ago that it is possible to have aux . A button for aux i dont have , idk how can i verify if it has. Its the Skoda Symphony from a 2003 skoda octavia that it has the option for a cd changer . Oh and i will verify one more time how i connected the bluetooth adapter to the 12v

I will atach a photo of the cd player here:

I may be wrong here, but I don’t think it’ll work with that type of radio.

There are other listings online for similar products, I would cross reference these and see what radios work.

While I like OEM. It’ll be easier just to check a nice single din radio in. It’ll be plug and play.

Dean , i have bought one , a sony 4x55 works fine but cant compare the quality of the sound . Thats why i tried to buy the bluetooth module. Thanks anyway:))
