Resuming Playback with 2014 CX-5 GT Tech Stereo and other issues

[EddieFord33]

There full of it, same here, promises and promises...Mazda is losing customers everyday because you cannot fool people in 2015 anymore.

I have called them and get the same run around...they hope you will stop calling and it will fall off the cliff one day...

GM is doing a masterful job getting people to buy their recalled cars. The Ford Escape out sells the CX5 5 to 1 and is the most recalled SUV on the planet. Mazda is not loosing any sales over this issue and continues to set records every month. People will never stop being fooled....

After reading, it seems to me like you have attempted to provide continuous power to the bluetooth unit when the car is off - is this done via the connection labeled AB in the bluetooth diagram? Can you provide details?

That's exactly it. The idea is not not mine nor is it new; I'm pretty sure someone suggested it somewhere on this thread. In my initial excitement I overestimated the effect on the BT boot up time though. In fact, the patch has no effect on the BT functionality as it is fully controlled by the HU.

 

[jtcx5]

I modified the wiring harness on the bluetooth module to disconnect AB from the ignition switched power (AUDIO2) and connected it to the persistent power circuit (AUDIO1). It works. USB resumes where it left off. I measured the bluetooth module using 2.3 mA when the car is turned off. I am hopeful that this won't represent a significant power drain on the battery.

The modification is actually very easy using 18-22 AWG T-Taps on the signals of interest and a short jumper cable terminated with 0.250 tabs.

 

[zorobg]

My measurements showed the same amount of current going through the AUDIO 2 connection. Basic calculations imply that the drain on the battery should be negligible, however over the Holidays I had a 3 day stretch where the car was not used and when I started it on the 4th day it noticeably stumbled. With the temperatures here consistently below zero there is some start hesitation in the morning, so I've disabled the mod for the time being. To me it looks that there is a significantly larger power consumption than the current through AUDIO 2 would indicate. I suspect that AUDIO 2 is only a signal input that in turn powers the BT through AUDIO 1. The only way to get a accurate value for the true power consumption of the BT is to measure the current going through both the AUDIO 1 and 2. It's too cold to play around with that now though.

 

[jtcx5]

Good point and there is another negative as well - the bluetooth module does not auto-connect to my iPhone anymore with the modification. I have to manually go to the phone menu and connect.

 

[zorobg]

I second that; I was hoping this is due to my not so up to date Nexus 5, but since you have an iPhone I'm now convinced now this is an universal behavior. To deal with it I've installed a delay relay triggered by the ACC that cuts the power to the BT module for couple of seconds on start (the USB can hold its status for few seconds w/o power); thus resetting the BT and forcing it to reconnect w/o having to do it manually. The timing as a bit fiddly as the ACC actually pulses twice on start messing up the relay timer. Question for you JT, did you isolate the ACC from the BT AUDIO 2 connection? I did so as I suspected AUDIO 2 is common for the BT and the stereo and by shortening it to +12V it will in turn keep the stereo ON as well. Did that happen to you?

 

[jtcx5]

I didn't connect all of AUDIO2 to AUDIO1, I only connected the BT module AB to AUDIO1 and I cut the wire from AUDIO2 to AB behind the BT connector. I put T-splices before and after the cut and on AUDIO1, so I can connect AB to either AUDIO1 or AUDIO2.

I discovered another problem - after multiple re-starts, USB quit working alltogether and the head unit just indicated it was reading the USB drive indefinitely. After this, I could not get it to work by re-starting the car or changing out the USB drive. After re-connecting the circuit back to it's original state, the USB started working again (without any resume capability, of course). For now, I have gone back to the original configuration due to multiple problems.

Let me know if you see any more problems. I may try some kind of similar delay thing on BT AB. What part did you use for the relay?

I hope that there is a way to make everything work as it should (USB resume, BT auto-connect and no lockup), but it may not be possible.

hi barkeyo,

Was just wondering did you eventually have any joy with a new usb module??I got the update.worked ok for few days then started playing up.eventually stops playing.if u format usb stick and put music back on,it will play ok for few days again until it goes corrupt.Just wondering if there is any point bringing back to useless dealer.Would appreciate if I could hear how you got on???im in uk too.

cheers

I hear you. I haven't given up yet on making it work, but the benefits are hardly worth the trouble. Even though my setup restarts the BT on every start up, the USB still randomly resets on its own, so back to song #1 it goes. Why it does that.. no idea; my best guess: its hard to improve crap. As for the setup, I haphazardly slapped together couple of 12V relays with a simple single transistor delay timer scheme downloaded off the Internets.

will those bluetooth fm transmitters with usb/sd card option work with cx5 with resuming last song played function?

Update on the bluetooth wiring harness modification - after securing the electrical connections better, connecting AB to AUDIO1 has worked without errors for a week. This modification, by itself, is an improvement over the default state of the car. Manually connecting your phone to bluetooth each time is better than the USB not resuming in my opinion.

I will soon try to install a DEI 528T pulse timer on AB to temporarily disconnect AB for around 2s upon starting the car, in hopes of getting the phone to auto connect to bluetooth. This device only costs about $15. If it works (both iPhone auto-connect and USB resume), then I am done and I can keep/tolerate the stock stereo. If not, I will revert back to the simple jumper wire. I will report back in a few days.

I don't know why it takes so long,but here in europe we can get reflashed modules.
I got it now for 4 months or so.
It's not perfect,but it remembers where it stopped for every stick you use.
You only have to complain "multiple times" before you get a nother module (that is what mazda has written to my dealer)
So we made it a game,I called 3 days in a row and he could replace the module

Hi, could you please tell what the module is? I'd like to have Mazda Indonesia knows about this module replacement so that owners of Mazda CX5 in Indonesia can have this resume last song in our cars, too. Since Mazda still denies this problem with us here, and it seems like their ignorance is pretty upsetting us.
Your reply will be much much appreciated. Thank you in advance.

 

[toeter]

It is just the bluetooth module that has been flashed with new firmware.
They switched my module with a used and reflashed module. Then my bluetooth module was send for reflash and installed in another car.
The reflashing can't be done by the dealer,but happens somewhere in the Netherlands.

Title:
Changed functions in combination with USB-connection
(only to be used when specifically asked by customer)

Description:
With the introduction of speech enabling the audio functions, some functions of the USB-connection have changed. After turning on the ignition:

BEFORE the modification:
1. The system reads the content of the USB device in order to activate the speech control, during this time playback is disabled (depending on the amount of audio files, this could take several minutes).
2. Playback of the connected device always starts at the first title (independent of where playback was at the time of turning off the ignition).

AFTER the modification:
1. Playback will start after approx. 30 seconds, reading of the remaining titles continues in the background
2. Playback will resume at the location it was stopped when the ignition was turned off

Reason
By introducing the speechcontrol the functions of the Bluetooth/Handsfree module changed, and the USB-connection is controlled by this module.

jt there are even less inexpensive delay relays on Ebay (if you wouldn't mind waiting for a while). I'm using one to give the BT 2sec reset on start up, but it behaves weird. It could be related to the cold as it's been below 0 here for I forgot how long.

After spending limited time with the pulse timer on the workbench and in the car, I was not able to get it to work consistently either (in above zero temps). I have continued using the jumper wire from AUDIO1 to AB and it has been working rock solid with no perceivable battery draining issues. I have logged 2+ weeks in this configuration and will probably leave it here until I get more time to try the circuit again.

I have thought about installing an SPDT switch to connect AB to either AUDIO1 or AUDIO2, as an alternative. This would allow you to set it to AUDIO2 if you are not driving the car for a long time. Could also switch from AUDIO1 to AUDIO2 for 2s, then back to AUDIO1 prior to starting the car. The problem is locating a suitable mounting point for a switch and finding time for the additional work.

As I posted in the CX-5 Introduction forum, my girlfriend was thinking about getting a 2015 CX-5 Touring. I could not convince her to wait for the 2016. Sure enough, it has the USB problem. For me, this is a HUGE deal. I kept telling her it was. The pandora worked satisfactorily with her S5, so it was no big deal for her and we ended up getting the car. I emailed Mazda and got this response:

While I get that its difficult to swap out the bluetooth module and all that, don't lie about it. "Normal" operation? Really? I sent an email back. Obviously it will go nowhere. We knew the issue upfront and to my girlfriend she was too worried about passing up a deal than to wait for a better vehicle.

It's the standard non-response a lot of the CS drones give out. It's 'normal' because it's not an unusual malfunction but rather a design issue. Irritating wordplay, yes...
