How will your Bluetooth module affect the operation of these features? I'm assuming that pressing one of the buttons will make a call to the On-Call operator via a Bletooth connected phone, and any features like remote car unlocking etc will not work... Is this correct?

to be honest i have never met the car with this system. so, if something from VOC is regarding phone call (dial a number, ...) then it will probably work. if there is also some data communication (GPRS, EDGE, ...) then it will not work.
i'm waiting for ordered parts. hope i will start with assembly next week. if you fill out the form i will be able sent it probably in the middle of the March because i'm able to make at around 3 to 5 pcs per week.

As far as I'm aware, VOC uses the same SIM card for all functions via voice and possibly via SMS. Obviously when using your Bluetooth module and no phone is paired, then any On Call function would not work; but would having your module fitted in this way be likely to cause errors to be logged by the car?

Is there any way to route the MELBUS cable from your module if the backup battery and cover are not removed from the PHM?

[marekbm]

yes, if the cellphone is not connected any function will not work. but i didn't implement SMS function because there wasn't a reason. and also it's not comfortable.
if you want to update PHM with the bluetooth module then it's probably better to turn VOC off. because if you leave the car then it's like you remove all SIMs (if it has own for the safety).
if there is space for the MEBUS cable then you just have to make a hole into the battery cover and pass the cable through.

I'm pretty certain that the built-in telemetry system is going to require its own SIM to function, so in theory if you have one in the slot, it could still work.

For 2012 onwards vehicles, VOC is a subscription service so it may be worth checking that any older vehicle still has the feature freely available.

the new version has been released. there is a feature for the simple test if the device is usable for bluetooth update. just connect the device, send the file "btphone_tst.btb" (part of the package) and you will see the result on the Dashboard (instead of device name). if all ok the then you will see "Test OK" otherwise some number is appears (let me know).
v2017-02-24_1
News:
- Bluetooth: Simple compatibility test.
Fixed:
- Modem: Added a new instruction used in the latest models (V/XC70).
- Modem: Missing connected device name on the Dashboard

It's disabled in default. To enable dial "*0#". After that you can manually connect second device. To deactivate dial "#0*". The second device will be disconnected and the audio is mode back into the first device.

Don't forget to update the user manual! I spent an hour in my car trying to connect two devices :-(

Seem to work fine, but I have maybe a compability issue regarding audio playback. If using my cell phone (Samsung Galaxy S5) there is no problem, but when trying to play same spotify app from tablet Galaxy Tab S (?) the music is on for 2sec, then stopping. I can press play again and then there is two more seconds of music. When the music stop, radio display indicate SAT channel change a couple of times and the song text is still showing but no music :-( any idea? Both units is last official android version.

Edit: regarding this playback issue, I had no problems with Grom audio wich I used before.

Edit 2: In manual there is an option for phonebook intelligent readout mode, but in menu I can't find M: Cont.int, onlye M: Cont.std and M: Cont.off Any idea?

Edit 3: Vehicle is 2007 V70 with HU850 radio.

the documentation is now updated (today).

regarding contacts:
there are only 2 options at the moment. if turned on (not changed in the firmware so its named std. yet) then it's like intelligent mode before. or you can turn it off.

regarding playback. which version of the firmware do you have?

I figured it out about the playback issue, if I have connected both phone and tablet I could play music without problems from my tablet, If the tablet is the only unit connected both Phone and Media sound via bluetooth must be activated. Strange, because this tablet is without modem and is technically not a phone.

Seem to work very well, except that I really think the sound quality is better when playing from my phone. When listening to the tablet sound quality is much worse. In spotify settings the quality is set higher on the tablet.

I have the latest firmware, v2017-02-24_1.

[marekbm]

i will check.

Also, I would like to discuss with you about how to enhance the sound from microphone. When talking to people in hands-free mode they always complain about sound quality. If speaking in the handset (PHM handset) then sound is good.

I assume that this phone design is from the early 90's and the technology is now much better, so maybe we could find a more suitable mic, and maybe also relocate it. I don't know where it is, but assuming it's inside the rear view mirror. Maybe mounting a new mic on the side of the mirror and pointing it at the driver?
