Default Android phone docking problem

Here is a strange problem. My Kyocera Duraforce Android phone was working perfectly fine with my 2007 xk for a few months, it would pair and dock seamlessly. Phone calls were crystal clear.

Then yesterday it would pair but not dock, it gives an error that docking failed. To verify that my BlueTooth on the phone was working correctly, I paired my phone with my wife's car and it worked perfect. I then also paired my wife's phone with the XK and it worked fine. So, both my phone and the Jag work fine with any other device but they refuse to work together was my conclusion.

I then decided to start all over so I went into the BlueTooth settings on my phone and deleted the "My Car" connection using the 'Forget' option and also deleted the pairing connection for the xk as well. I also restarted my phone for good measure and restarted the XK. I then tried to pair them up again and that went fine, but once again the docking failed.

So now I am wondering what exactly does docking do and what would prevent a phone from docking?

Another note* my wife and I have the exact same phone and the exact same software versions and yet her phone pairs and docks and mine does not. How strange is that?

If I can't get this fixed then I will ultimately swap phones with her but I would rather avoid that headache as hers is full of pictures, contacts and apps and moving everything over is a hassle.

Thoughts?

Sorry about your pain. To address your questions about pairing and docking:

Pairing allows to devices to see each other and theoretically work together. Once paired, they are always paired so each time they are within an acceptable distance from each other, they pair. Be aware that while most devices see each other and can be paired, not all functions will always work on the devices once they are paired.

Docking, simply means that some of the phones functions are viewable and usable via the Jaguar's touchscreen.

Why this suddenly happened to your car with no upgrade to the operating system or Bluetooth version on your phone, I can't explain.

As you know, Jaguar doesn't keep up (and who could) with all of the new phones and BT versions. Each Android operating system has given different phones different issues with BT connectivity. Lollipop was a big one, Marshmallow solved some but created others.

The only know current solution that I'm aware of it to get a newer BT module or as you suggest, an older phone.
A newer module, meaning 2009 or newer and with that, you will probably still not see your directory, just your last 10 calls.

OR, do a hard reset on your car as sometimes that helps weird problems.
Disconnect the negative battery post and touch the negative cable to the positive cable for a few seconds. Most of your settings will need to be redone, but it may also fix it.

f22 in the Auxiliary Junction box powers the BT module. I don't know if there are any capacitors in the module, which is the reason you disconnect the battery cables and hold the cables together (to drain any voltage in all capacitors), so I'm not sure how long it would take for any to naturally discharge.

The module in my 2012 is located to the right of the battery in the rack . There are a few other modules there and I don't remember which one it is.

Oops, sorry I didn't see this question. The BT module is, as Jagtoes mentions, the stack to the right of the battery and the module just below the Navigation DVD player. There are three attachments. Power, antenna and MOST fiber optic cable. Then it's held down by 4 8mm (or 10) nuts.

So if you remove the cover to access the unit, it's actually easier to disconnect the battery cables and hold the together for a minute to do a hard reset as Cee Jay suggested.

Im having the same problem with my Galaxy S7...it used to work fine and then all of a sudden wouldn't. I haven't tried the hard reset so maybe I'll give that a shot. Its frustrating

Check for phone updates as the SW changes may be causing the problem.

Keep your eye out for 9W83-10D893-AA or AB on eBay. Those are the later model BT modules used in 09 and later XK's. They can be pricey but if you're patient you can find them for $150 - $175.

I don't know what the cost is but Cambo mentioned on this thread that he can now update the earlier bluetooth modules to the later firmware so that might be a cheaper/easier option:

Bluetooth, including part numbers and experiment

I just hate doing a hard reset on a car like the XK. With my luck something will go out of wack and won't go back to normal. Not worth it. I pulled the fuse and will wait 24 hours and see what happens when I try to pair it up again. Otherwise I will swap phones with my wife and problem is solved.

Good news - phone is working again! Hooorayyy!!! I did a safe mode restart on my phone [I did not even know this was an option before] and it started my phone without any extra apps. I then tried to pair and dock and it went seamlessly. Then I restarted the phone in normal mode and it failed. Looking through my apps I found the culprit. It was a BlueTooth app that I used to use for my job that was screwing things up. I removed the offending app and all is good now. So if anybody else has this problem maybe safe mode will work for you like it did for me.
