Bluetooth Navtool OnePlus 5t phone calls problems

I am not sure if this is the correct board to post the question.

I have an Acura 2009 TL SH with Tech package, Navtool (for android auto), and an Oneplus 5T phone. Every time I make a call, it starts with bluetooth on and then when the call connects, it goes to phone or speaker on the phone. I always have to change the connection back to bluetooth and it works but sometimes by the time I do that, the caller on the other end hangs up because they cannot hear me until I switch back to bluetooth.

My question is which device is the problem? The HFL in the car, the Navtool or the Oneplus 5T.

Thanks

More information:
1)I disconnected the bluetooth between my car and phone (Oneplus 5T).
2)I connected a headset bluetooth to my phone (Oneplus 5T) and when I made a call through android auto, it worked fine.

I did not try another phone because I do not have one handy right now.

My question is:
Do they have an aftermarket hfl bluetooth or firmware upgrade?

Thanks

I also pulled a bluetooth log from the phone which I can send if someone knows how to read them. I tried opening it in Wireshark but not sure what to look for in the logs.

Thanks

Call transfer problem

So after researching two weeks, I found my car has this feature called call transfer. Anytime you make a call from the phone, you have to manually transfer the call.


When calIing from android auto, it is the same as calling from your phone. This is very inconvenient because the other party sometimes hangs up before you transfer.

Does anyone have any suggestions?

Can I try replacing the infotainment or HFL module with newer version?

Maybe an automated script on my phone that changes it on the fly?

Out of ideas that work.

Thanks

How are you making the call?

I ask because in my 2006, if I use the HFL to initiate the call, as in "Call Wifey", "Do you want to call, wifey?", "Yes", "Calling"; then the phone stays connected to the HFL the entire time. However, if I pick up the phone and trigger a call from it, then yes, I need to indicate I want the call to be routed via the Bluetooth versus the phone itself.

Horsehoez,

Thanks for replying so quickly.

I installed Navtool Android Auto in 2009 TL with Tech package. The way it works is you hold cancel for three seconds and it changes the display on your car to android auto. I use android auto to make all the calls with the jog in the car. It is the same as making a call from the phone.

Thanks

Your car is a 2009, it was made when bluetooth in cars was just coming out. I'm sure the actual design of the bluetooth system is even older. So, it is the design of the unit in the car and has nothing to do with the Navtool setup. How the bluetooth system in the car works is that if you use the car to initiate or answer a call then it comes through the speakers on the car, if you use the phone to answer or initiate a call then everything is on the phone. However, on the car, if you transfer the call from the phone to the car, then you would now bring the call to the car. If I make a mistake and use the phone to make a call, then after the person answers, I transfer the call to the cars bluetooth system.

I also have a Navtool system. When you switch to the navtool display, it only overrides the display, it does nothing with the actual Acura system or bluetooth system. I use my Navtool only to display a forward facing night time camera system. When I use the Navtool I realize I no longer have access to all of the features of the Acura system that requires the display to use.

Its just how the bluetooth on all 4th generation Acura's work, nothing wrong with your system.

Thermoguy,

Thanks for replying. It just does not make sense why the model without navigation has an option to do auto transfer but with navigation they do not give that option.

I sent an email to hands free link. Let's see what they say.

Thanks

My car has navigation - I have a 2011 TL SHAWD - I have the option to transfer and it is the only way to switch the call from your phone to the car speakers.

What do you mean by auto transfer? Are you suggesting the phone will switch from the handset to car automatically without initiation by the user?

Correct. This option was implemented on Acura 2012 TL with tech package. I found this by looking at the manuals on the Acura site. It has an option that will automatically transfer the call from phone to HFL.

Thanks

Do you think taking the HFL module from a 2012 and installing it in my 2009 would work?

I have no idea but I wouldn't imagine it would be worth the cost.
