CPMC device and BMW App

[Lupo]

Hi,

I have a CarPlay device (CPMC similar to Aoocci etc) on my 1300GSA and I have noticed that it won’t play audio via my Sena SC2 without connection with the CPMC in which ever App I may be using at that time (Tomtom / Mixcloud / Spotify etc). This means every time I switch the bike off (fuel stop etc) I have to get my iPhone 13 out and re-connect to CPMC in the App……Once I connect via one App it then works for all Apps.What adds to my confusion is that I can still open the App of choice on the CPMC, I just can’t hear the audio with out following these steps. The device tells me to use the vehicles volume controls??? - which is a PITA.

I am wondering if the BMW App/Bike is overriding the CPMC and Sena…..and I need to ‘forget’ BMW Motorrad App on my phone? That would be disappointing as I like the data…..or whether there is work around, has any one else experienced this?

Possible... just get rid of all connections to the TFT and connect both your phone and sena to the CPMC.

I have the same device. I connect it to my phone as a CarPlay device and then my Sena is connected to my phone for audio. All the CPMC does is the visuals; the headset remains connected to the phone. Seems to work for me.

Cheers guys, I will have a play.

CPMC, AOOCCI, a n other from somewhere else, are all the same unit and the destructions say wot Cadmium said but I've not tried mine in anger yet

Thanks for replying, I plan to have a play this weekend but I thought that was what I had done……perhaps not.

I watched it, thank you……if I switch the Sena on after the B6 (which has connected to the iPhone first) then it all works and I can stay connected to the bike also. I need to trial it a few more times, your video has explained why is happening and if my way doesn’t work then I will use your work around!

You're very welcome, fingers crossed!!

It's nothing but trial and error sometimes

Hi, I tested the setup I mentioned and it worked for a while then stopped but ‘rebooted’ a connection after I switched the Sena off and on again. I did this twice during the day…..I disconnected the TFT after the first time and the connection seemed more stable. It looks like my only option is to use the B6 as the ‘hub’ on the GSA but I am unsure about this because I will have to tell my phone to ignore the Sena and that creates a problem - I use another bike most days, which doesn’t have the B6 on it, and I want my Sena to connect to my phone. I might have to live with the GSA issue, but at least I have a kind of fix.

Would the Sena have the capability to connect both phone and GPS at the same time? I know Cardo has that capability.... so forgetting about the TFT, using the B6 as hub and maybe having the Sena using both profiles where you can switch from one to the other would solve your issue switching between bikes.

Not sure, just a thought!

Edit: Quick google search tells me that yes, just like Cardo... the Sena has 2 profiles. So you should definitely try that, your phone as primary and GPS as secondary.

Super, I will try that….. thank you for your help!

Has anyone tried or had any issues connecting a CPMC B6/B7 unit to a charger via the USB port please?

Has anyone tried or had any issues with connecting CPMC B6/B7 unit to charger via the USB port please? - Thanks

It’s the same as the Aoocci unit, your charger needs to be above 66 watts apparently, otherwise it just restarts over and over

Try using a laptop charger

Hi - Thanks - I did actually try a 106W charger and nothing doing. The unit works on the bike so perhaps the port is 'broken'. The 'instructions' quote a low power charger which I tried (in vain!) but I was just wondering if anyone had ever used the USB port at all!

I’ve used it to power the unit when doing a firmware update, that’s how I discovered the issue above

Tried that thanks - no luck

Thats good to know - so I do need the port to work!

So the B6 and B7 on the bench with a usb cable, at least the original from China land, will power up on 5v usb-c. It takes a little bit over an amp.

The problem, at least on the unbranded version from WEUASTE, is that the unit requires more than 5 volts (it will power up, but NOT if set to full brightness ...if you can catch it in time to turn that down, it will stay on)

What I did was make a USP-c cable with a PD Decoy for 9 volts in the smart charger end. The decoy triggers 9 volts, the charger powers up and the unit runs perfect on the bench from usb.

I hope that maybe helps.

EDIT add: It is not the power of the charger, it is the voltage, so you need a smart charger, and a decoy to trigger it to 9 volts. There is no usb PD negotiation built into the units usb port at all ...or turn the brightness down to 30% when on the bike, then on the bench it should stop continuously rebooting
