Help Bluetooth no longer works with vehicle after network reset

[RVX]

I was having some issues with my wifi recently, so I performed a reset on my network settings. This fixed my wifi issue, but now my Bluetooth no longer works with my vehicle.

I have a Boss BT speaker that I was able to pair after some headache, but I just can't pair my phone with my vehicle anymore.

The vehicle in question is a 2015 Acura MDX that doesn't have Google software installed. I was able to pair my phone in the past. I would set my vehicles audio source to BT, and my phone would detect "HandsFreeLink" (which is the BT name of the vehicle), and they would pair.

Now, I'm not sure if my phone sees my vehicle. When I search for BT devices, it never shows "HandsFreeLink" anymore. It just shows a list of MAC addresses. I'm not sure which represents my vehicle. I tried connecting to all of the ones in range (it shows a lot no matter where I am.. I should drive out to the desert and scan from there to make sure I just see my vehicle I guess).

I will randomly get message pop ups on my screen saying HandsFreeLink wants to pair with my phone, and will give a key number, but sometimes I can't click "ok" before it disappears, and other times I click "Ok", but it still fails to pair.

What I've done so far to try to fix it:

1) I've reset the settings again. No effect.
2) I've cleared my BT cache. No effect
3) I've ensured my phone is visible. No effect
4) Rebooted the phone (obviously). No effect.

I am at a loss at this point. I don't know what else it could be, and can't imagine resetting network settings would destroy Bluetooth functionality on my phone.

Any help would be appreciated!

Also, from the vehicle, I tried adding a new device (Pressing the Phone button on the console, which displayed all the phones that had paired with it in the past, including mine), and chose New Device. My phone would not show up on the list of neighboring devices that the vehicle can see, even though my phone visibility is on, and as mentioned above, my phone will get random messages from HandsFreeLink (the vehicle) asking to pair, and displaying the key number. Tapping Ok on the message never works, and sometimes the pop up closes even before I can click OK.

Reading through your description it sounds like you've focused more on your phone's Bluetooth but what about your Acura? You mentioned an option to add a new device but is there also any option to delete old pairings? Bluetooth being a low-powered, limited-range form of networking when you did that networking reset it also returned all Bluetooth settings in your phone back to their defaults too so if your car's Bluetooth retains the original pairing with your phone's Bluetooth address that might be creating some kind of conflict with your phone's current Bluetooth address.
To check if your car is seeing your phone's Bluetooth address, look in your phone's Settings >> About phone >> Status menu (that's where it is on the phone I'm currently looking at, most likely similar but not the same menu path as your Galaxy A5). Is that Bluetooth address showing up on your car's menu?

Thanks for the reply. I'll have a look after work.
