Hello.
For your information, it doesn't support to connect other Bluetooth devices when you’re using wireless Zlink(CarPlay/Android Auto),
cuz the Bluetooth access has been occupied by Zlink.
If you want to want to connect OBD, please make sure that you have disconnected Zlink firstly.
@Support Dasaita That is fine if the OBD2 option does not work. I have tried it with and without the phone, with no luck. That is not a big issue. It seems like Bluetooth should connect to multiple devices at the same time. I would like to focus on the bigger issue that had since the unit was new.
How are you going to fix the phone/microphone/car play issue? Per the last message, I did the steps you asked for.
@Ryan Ouellette
Hello.
We have helped you forward case to our technical department.
Now our technician is working hard on new update software.
If possible, could you please wait for it then test how it goes?
Once new software available, we will send it to you immediately.
Besides, please tell us the result about the operation we asked.
(Remove adapter PJ-HM01 with a Sony external mic then reconnect the standard external mic that comes with parcel to check if it can work).
@Support Dasaita I have removed adapter PJ-HM01 with a Sony external mic and then reconnected the standard external mic with the same result. The standard mic works on bluetooth but sounds bad, and does not work at all with Carplay. What is the most current BT version, and I'm I running the most current?
@Ryan Ouellette
Hello.
For your information, your current system version is the latest one, thus BT also is the newest.
@Support Dasaita Great. Any idea when your engineer will have a solution to the issue? I would like to be able to use my microphone on phone calls.
@Ryan Ouellette
Hello.
At present, our technician is testing the new update software.
Once it available, we will send it to you immediately.
Thanks for your understanding and patience in advance.
