Introduction - The Story
Longtime Ghibli owners know how bad the Bluetooth functionality of our UnConnect / Maserati Terrible Connection (MTC) is. On some days it would work normally, other days it would refuse to connect to any device. Repeated dealer visits and replacing the HFM module yielded zero success. My dealer flashed the HFM module firmware to the latest version, which gave me song metadata but still didn't solve the issue.

The dealer then told me there were no further firmware updates and that I just had to accept the BT functionality being unreliable. Inputting my Ghibli's VIN on UConnect's update website lead to an error saying the VIN was invalid, which makes sense since Maserati rebranded it to MTC. Even though I have already installed a wireless CarPlay unit, I still wanted BT to work since this specific music app I'm using has an official DTS surround sound plugin which sounds terrible over CarPlay and USB but would sound phenomenal over BT. Yes, I eventually took the risk of bricking my radio over trying to slightly improve audio playback quality.

I wanted to know if there are any updates at all for our UConnect. I knew that our radio, the RB5, is also used in Dodge Charger, Chrysler 300/300C, and some Fiats. I also knew from installing my own navigation maps that it is feasible to flash the navigation firmware from a Dodge Charger into a Ghibli to downgrade it to CTP13 so we can flash the new maps ourselves. I also knew that my UConnect has a software version of 15/09/D1 from the dealer menu. With all that, I Google'd "UConnect 15/09/D1" and lo and behold, there was actually a new update issued in early 2017 with the version 16/21/D7!

The patch notes:

TSB 08-004-17 refers to a software update for your Uconnect system:

"NUMBER: 08-004-17

• In “Set Date Year” only 3 digits are displayed.
• Split map view will not cancel.
• Map screen turns black when driving.
• When in Italian, the destination arrival text will overlap onto the map.
• Does not accept Iraq when commanding “Set Target Country”.
• Some pop up message characters are displayed with “!#”.
• Traffic programming slow to start."


The line I highlighted caught my interest. Could this be the long-awaited BT fix? I decided to get my hands on a firmware update for Dodge Charger and risk it. Since we could downgrade our Garmin with their firmware, then surely we can upgrade our UConnect with their firmware too...

Why we didn't get this update? My guess is Maserati had already moved on to MTC+ by then (MY2017) and did not want to spend time on fixing older radios.

--------------------------------------------

Obtaining the New Firmware Image
How can we download the new firmware if the official website doesn't take our VIN? I went on CarGurus to look for a Dodge Charger for sale with the same RB5 nav as we do. Here is the VIN I used: 2C3CDXHG0EH321930.

Go to UConnect's update website and paste in the VIN: Software Update for Uconnect® - Check For Updates

Then, just follow the instructions presented to you. I wouldn't do the navigation update to CTP17 since some people imply it might disable downgrading to CTP13 to flash maps without a dealer visit.

A caveat though: I had to format my USB drive to FAT with Master Boot Record under macOS. For whatever reason, UConnect could not read my drive when I formatted it under Windows.

The update should take no more than 20 minutes. I recorded the process and here are my initial reactions:

SW version before the update:
20444


The update prompt when the USB drive was inserted:
20445


During the flash:
20446


After the firmware update:
20447


Observations
Removing paired devices is much faster and the pairing process is also a lot faster. I will need to give it a few days to see if the BT issues have truly been fixed. You are all welcome to install this update and see if the BT situation has improved!

Thanks for reading!

Following. Nice work. Hoping this is a solution for MTC (2014-2016) owners. Question, how does one install wireless CarPlay on a 2014-2016? Just curious. I am using a Carlinkit Dongle, but this is for cars that have wired CP already.

Excellent work! My car has an even older firmware version than yours (13/50/99). If I follow your instructions will it upgrade to the most current version, or do I need to a “pre-update” first?

I look forward to hearing how your system is working in the upcoming days.

Nice Work! I just performed the update from 15/29/D7 to 16/21/D7. Phone was able to connect both times I started car so far. Fingers crossed that this fixes the problem. Once again, thanks to AlphaWip for taking the time to try and figure this out.

You would need to disassemble the dashboard and stuff a CarPlay box behind the screen.

I’ve seen people asking similar questions on Dodge forums but didn’t really pay attention to any answers. I’m not too sure if you need to update it to 15 first.

I performed the update and everything initially worked well. My firmware was updated from 13/50/99 to 16/21/D7 without any glitches. After the initial restart, everything look great and I even saw a screen explaining how the VR button on the steering wheel can be used for Siri commands (this was a first).

I had a few errands to run, so after making my next stop, I shut the car down as usual. But when I came back to the car, Bluetooth would no longer connect.

I tried everything. I even deleted the profile from the car and my phone and tried to reconnect. Nothing! Again, I got the issue where the car stops sending a bluetooth signal. So I couldn't even set my phone up as a recognized device until it decided to start functioning again. Ultimately it allowed me to re-establish the Bluetooth connection after about 3 more trips (with full shut down and start up).

It looks like things are just as bad as before for me. It’s promising to see that others are having success. It looks like I will need to go back to the dealership and see if there is a true hardware problem somewhere else. Within the last week, I have had the handsfree module replaced and updated my firmware without resolution.

**** it! Looks like I called it too early.

FYI on UConnect’s website, the last supported iOS version for our RB5 radio is 11.2.6... SMH

Question: I saw that you were able to display song meta-data after a dealer firmware update. Does that mean the MTC display actually showed the Artist and track name when playing music from a mobile device via Bluetooth? My 2015 current just displays the name of my phone.

Yes, artist and track name. Ask them to check your HFM firmware.

I kept digging and logged the BT traffic between MTC and my iPhone. I have successfully identified the EXACT problem that prevents MTC from connecting to our phones.

Here is the log for a successful connection:
20452
20453


And here's the log for an unsuccessful connection:
20454


The single error that prevents MTC from connecting to my iPhone is: Connection Response - RFCOMM - Connection Refused - No Resources Available

I looked up the error online and it was very scarce. This post was somewhat relevant: https://stackoverflow.com/questions/52145779/linux-bluez-rfcomm-connection-refused

Interesting excerpts from the StackOverflow link:
"Q: ... The device was successfully paired. An RFCOMM connection to that device from Android or Windows can be successfully established, so the problem seems to be locaed with Bluez diver and/or blueotoothd.
With Linux/Bluez the bluetoothctl and Wireshark traces show that it fist connects and then after about 2 seconds a disconnection is done. The reason for the disconnection is not clear.
...
The same problem happens with different Linux releases...
...
I have checked numerous other thread having the same/similar problem. Most have no or no clear answer.
...
"
"A: ... This often happens when bluez doesn't have all the mandatory profiles which the device needs.
...
The incorrect RFCOMM channel was used. It instantly works when the correct RFCOMM channel is used.
"

Linux Bluez = the official Linux BT stack. If MTC is indeed running on Linux (which I suspect it is), this is probably simply an issue of misconfiguration or outdated Linux BT drivers.

Something else I observed: It seems MTC is still active and attempts to connect to my phone after the ignition is switched off and the car door opened.

Right now my hope is to unpack the KWI update file and see if I can mess with anything.

EDIT: Someone with the same symptoms (a different BT device though) and the engineers providing a solution: L2CAP connection refused with BLE_L2CAP_CH_STATUS_CODE_NO_RESOURCES - Nordic DevZone

Relevant Linux BlueZ source file: https://github.com/edrosten/bluez/blob/master/monitor/l2cap.c

AlphaWIP, that is amazing work. I consider myself reasonably technically literate, but this definitely went over my head. I have an appointment with my dealership next week.

I already did the MTC firmware update. Is it true that there is a firmware update for the handsfree module itself? When my phone is connected by Bluetooth, it does not show the artist or song name. The screen only shows the name of my phone. If there is another firmware update needed, this may help things a bit. My connection has deteriorated from 6-7 out of 10 to 1-2 out of 10.

I ultimately would like to have a Carplay system installed, but I want to make sure that my Bluetooth problem isn't a sign of another problem that would render an aftermarket system inoperable. Otherwise, I wouldn't devote so much time and energy to a solution.

Yes, there is a separate HFM update.

I've been attempting to dissect the KWI update file. I initially thought this was a standard Kiwi format used in the majority of Japanese-made radios (See here: Kiwi-W Consortium) because UConnect 8.4N is technically a Panasonic unit but the Russian-made KIWI file extractors could not read the file. I then used binwalk, a tool that specializes in firmware format identification and did an initial signature scan. The results are as follows:

This paper is an interesting read that shed some light on the inner workings of UConnect radios. According to the paper, the Bluetooth module is on the CAN bus. Granted, it’s the RA UConnect they’re talking about but I’m really curious if we can read messages emitted by the HFM on the CAN bus.
