Yes, this is super old. I have an android. Its not the phone in my opinion when the car's bluetooth wont even search for any phone. Click search and nothing happens. Seems like the car, not the phone,

 

Try pairing with the car in accessory mode, engine off…worked for me…

 

The Bluetooth modules in these cars are known to go bad. You MAY need to get a replacement if none of these fixes work.

 

I would suggest you get a Tesla style Radio.The Jaguar system is 17 years old...that's almost a dinosaur in electronic age...

 

I'm having this same issue in my 2012 XKR... I noticed my android phone suddenly didn't pair, and when I went to the phone screen from the main menu, it says ""would you like to search for a new phone now?" And a single button that says "YES", but selecting it does nothing.

When I connect my iCarSoft reader to the vehicle, trying to read codes from the cellular module gives a link error, like it's not present. I can't recall if this used to work or not. Can someone confirm?

If the module is bad, I'm not sure what module I should purchase. Looking through part catalogs, it might be C2C25796... But I haven't seen ANY used modules with that part number on eBay. That doesn't seem right to me, and it makes me second guess it's correct. Maybe I should search for something else?

 

Before anything else, check your battery voltage after sitting for several hours. It HAS to be 12.6 volts or more. If not, you can try to charge it with an actual CHARGER of 10 amps or so until it finishes. Trickle chargers or maintainers won't cut it.
Also, doing a Hard Reset sometimes fixes a lot of electrical issues.

 

I have a NOCO G7200 charger... Are you saying that's not a recommended product?

If I end up getting the car I’m looking at getting this one.

 

For using as a maintainer that one is great. To do the heavy lifting when a battery is quite flat it isn't ideal since the maintainer types lower the output by a lot for the top whatever percent of charge. They just aren't made to CHARGE a battery, just do the last bit safely and reliably.

 

My battery is definitely not dead. My radar detector shows a running voltage of 13.5, and even when I just put the car into run mode without starting it in the morning, it's never below 13.2v.

I've put it on the charger overnight just to see if the module connects tomorrow.

My Bluetooth module is a 9w83-10f845-aa, which is not the same module as C2C25796.

 

@TraxtarXKR , once you get you battery issues sorted, you can look for the one you have. THese are backward compatable technically but they can't keep up with the ever chang software of cell phones. 9w83-10f845-aa is the latest and last of the modules made for the X150



There is also this thread where @Hockey_Steve had success installing a Volvo BTM - https://www.jaguarforums.com/forum/x...solved-256378/

 

My 2012 XKR (B46623) uses 9W83-10F845-AA... So that list is off for that revision number and applicable VIN number and model year.

 

there, fixed. removed the date range and part numbers. You still have the last built for your car. Or jump over to the link I sent you. You're welcome.

 

Thanks Sean. I've seen that list of module revisions used in a few Bluetooth threads, and there's a gap in the vin sequence that mine fell between. I'm not sure how early 9w83-10f845-aa started going out with vehicles, but it's at least 2012.

I just bought a used module on eBay from Noma Auto but it was the previous revision and the listing title was wrong. They're accepting the return.

I followed the Volvo thread, but it ended with the need to solder in some resistors for the antenna and extend a MOST cable, and I'd rather not do that.

 

I hear you about the Volvo BTM but are you sure Hockey Steve did anything other than plug and play. I know when @Bill400 first provided input he may have suggested it but to me it reads like Hockey Steve just bought one and it was plug and play. Late Bill alluded to some models that had poor reception but those were different? Anyway, I'll keep my eye out for your model and PM you if I find one.

 

Previous discussions about BTM (including Bluetooth Module - apparently dead (RESOLVED) - Page 2 - Jaguar Forums - Jaguar Enthusiasts Forum) noted that Jaguar, Land Rover, Volvo, Aston Martin and others have used the same module as noted by the FCC ID. There are two IDs, that all use the same Motorola chip and circuit board. The lack of an external antenna does not inhibit phone connection, in my experience. Generally, the "other brand" modules are plug and play. However, as noted in the previous discussion, the original software for Volvo modules may not be recognized by JLR SDD. I was going to "force" the software to the latest JLR, but my unit works fine and BTM efforts got lost on a back burner.

I haven't tried it, but I expect that earlier production XK BTMs will accept the later software as an update, using SDD.

 

For these simple bluetooth connections, I think you will find the bluetooth standard is backwards compatible .
These modules need to be "recognized" as a compatible "remote". Typically the issue is that the phone is not in "pairing" mode during one's attempt to pair.
Anyhow, I do have the latest iphone and an '07 with the original module. There is no issue.

 

A little while ago, maybe during COVID, BTMs for anything except Jaguars (especially XKs), were dirt cheap. So, I bought some of the ones with the correct FCC ID to experiment.
I discovered that they all used the same Motorola chip and circuit board. The integral BT "F" antenna consists of copper traces on the board in the shape of an "F".
The integral antenna is present but bypassed on XK BTMs. Also, the footprint for the external antenna connector is present on all circuit boards.
Some production models consolidated and/or reduced the size of the components used for impedance matching, that is, loading the "F" antenna. Otherwise, the circuit boards and components appear to be the same.

Motorola appears to have begun production in France, then moved production to China. The Motorola Division responsible for design and production was sold, which appears to coincide roughly with the change of FCC IDs. Confusing though, is the LHJ portion of the ID, which indicates the owner, remained the same. Further confusing, units with the different FCC IDs were produced at the same time.
A Motorola location in Florida was "responsible" on one of the FCC submittals, so, I requested a schematic or other information but was ignored.

Software: capabilities were definitely improved during the life of the unit. The number of stored contacts was increased, and the BT version was almost certainly updated.
As noted on a previous post, using the Volvo BTM/software as plug-and-play can work fine in an XK, even with the integral antenna. However, it may not play nice with SDD.
SDD version 138 ignored the Volvo part number and performed unrelated tasks such as programming fobs, without blinking.
SDD version 147, however, did not like the "foreign" part number and refused to reprogram fobs.

Reprogram Volvo BTM as JLR? What is the issue? The software in the BTM contains a part number that SDD uses to "resolve" which software that it is allowed to load into a module.
The scheme is part of that "designed by geniuses to be carried out by idiots". SDD does it's best to prevent "your mistakes". Highly competent techs could use a programming tool to load the software directly to the chip. (I'm not there yet.)
Alternatively, SDD can be altered to expand the "qualifiers" to include the Volvo part. (Do-able.)
But the best bet (I think) is to use the "bait and switch" technique: Use SDD to reprogram the BTM. Begin with an XK BTM in place but substitute the Volvo part just prior to the actual programming.
That is, a hot switch of parts at the last moment.

That's most of what I found.
For those who are interested, I'm happy to discuss.
PM, email, post here or a new thread is OK for those so inclined.

To those who think it is TMI, I apologize.

best regards,
Bill

 

Having the exact same issue with my 'phone module as shown in the first post, co-incident with the info screen cycling off / on Intermittently. The 'phone module is In the same fibre loop as the info screen; disconnecting the fibre plug from the 'phone module causes the info screen to blank out, as expected. Looking in the plug for the fibre loop at the telephone module, I can see the red illumination for the fibre, nothing coming out of the module. Pulled the module out of the trunk, pried off the cover, and reconnected the board minus the case. Module now working. Reassembled in its case, worked for a day, then failed again. Suspect intermittent. Going to check supply voltages (and grounding...) next. Incidentally, noticed the Tele unit has a FoMoCo number on it; for those looking to wholly replace the unit, might be a cheaper alternative to a Jaguar unit.

I have the same unit as @TraxtarXKR I think but don't use it. I have Car Play instead. I'm just keeping the module for the day I sell, if ever, for the purists out there. They usually pop up on eBay for around $300 now and again. Yikes though, I don't use my phone enough to care.
