Convert COMAND 2.5 tape deck (cassette) to AUX input
http://www.insightcentral.net/forums...nger-free.html





I did this mod weekend just gone. All working fine... But... I get interference when I have my phone connected to the aux cable and have it on charge at the same time. The speakers on the drivers side cut out... Anyone else had this? Any ideas what it could be?
So i removed my Comand 2.5 and removed the tape deck and did the steps as mentioned by OP, but I tried to withdraw power from the tape deck instead of having to get wires all the way from the lighter. (which didn't work, so I guess I have to take wires from the lighter).
I connected Left, Right and Ground as advised in OP without cutting the traces because I have a cassette which is blank, I got audio from the AUX I attached via my phone instead of that fancy bluetooth transmitter, but it's very very low, is that because I didn't cut the traces? If I cut the traces as shown in the pictures above will the audio quality be better?
please help my comand is all removed till I find a solution and I live in the middle east so driving without A/C as horrible haha
appreciate any help
You should definitely cut the traces, even though you use a blank tape the audio heads still read a signal from the casette and that is what muffles out your audio, I myself have done everything exactly as shown on the pictures and the audio quality is perfectly clear

Thanks for your reply
Okay I did cut the traces and now I don't get audio from anywhere!!!
I unplug then motor cable and slide the wheels all the way to the play position and I get "NO TAPE" then I inserted my bluetooth tape (blank tape) and got "Tape Error" then I plugged back the motor cable and it switched from "Side 1" to "Side 2" then displayed "Tape Error" again!
The only way I could get audio out is if I manually turn the wheels as if there was an actual tape working

PLease help now I can't use my bluetooth casette or the aux port!!
I even tried different Aux cables (They all are functional) but not in the car

I've done more or less the same thing as what he described, but also attached a CSR8645 5V Module (you can find those on eBay and Aliexpress - make sure you don't buy the 5W+5W ones !! - the 12V ones are more popular on eBay it seems, but most sellers if asked will ship you a 5V version).
And now, here's the full tutorial:
If you're interested in Bluetooth mods but don't fancy soldering, I can probably hook you up for a pretty penny (I live in Germany).
