I’m new to the forum so maybe this has been discussed before but has anyone lost their radio antenna signal, especially for AM after getting window tint installed? I’m working off my iPhone and haven’t discovered yet how to get to old subjects. I have a 2007 XK with the electric antenna mast.
Thanks

This may sound stupid, but do it anyway.
When window tint is installed, the doors are left open which drains the car battery.
It's almost always the battery, for nearly everything.
SO, recommend you get the battery fully charged. No maintainers or trickle chargers but an actual CHARGER. For 24 hours.
There are also a few threads in here on antenna connectors and such, but you'd have to search and such and that's tricky on a phone. Especially an iphone.
Here's a pic that MAY help though... and the direct web link:

Thanks Cee Jay. I recently replaced the battery with a glass mat battery that solved other low voltage issues but no luck with the radio. My second battery in 7 years. I did purchase a bluetooth FM converter and use my iPhone for lots of radio and music options, though the sound quality isn’t what normal Bluetooth is. Thanks for your help. I’m finding out the iPhone isn’t the way to navigate the forums but it’s all I have.
BTW I replied to you by hitting the (QUOTE) button. Is that correct? Seems odd instead of a (reply) button.
Thanks

Not sure what your VIN is but this is the only TSB I can find on it: IAM = Integrated Audio Module AKA CD player. Also check fuse 21 in the Auxiliary Fuse panel. I think the Cee Jay is right about the battery.

 

My VIN fits as suspect in the TSB you sent and manufactured in 09/06, so I will follow guidelines of the TSB and also check the fuse. As I mentioned to Cee Jay I recently had a new AGM battery installed but I will put my charger on it for 24 hours too.
Sean, please let me know you got this message so I know if I am communicating on this thread properly.
I really appreciate all your help,
Jay

 

An fyi, though many have done it, your MY does not have the appropriate generator nor the BMS system to properly support the AGM battery type.
As @Cee Jay implies, there are significant electrical demands of the car. These modules and components require a specific voltage and amperage. Any insignificant deviation will cause any number of modules to shutdown.

Cheers.

 

Thank you. Once again the importance of battery voltage. 👍🏻

 

Yep I see your post Jay.

OK a word about AGM battery - Jaguar supplied some models with AGM batteries. The workshop manual says replace like for like battery. The vehicles that have the start/stop function, of which the X150 is not one are the vehicles that came with AGM. You may read that the alternator outputs are different and all sorts of fun things but the truth is many many Jaguar X150 owners have AGM glass mat batteries with zero problems. Truth is I probably contributed to some of those conversations but @GGG gave us all the skinny on the origination of the AGM through his sources and it should be in everyone's rear view mirror. Also, many new owners have no idea what battery their car came with.

@Cee Jay is spot on. Tint the windows, leave the doors open while doing it, drain the battery. OK so there's that, and it's getting beat to death. Sounds like you get it. Put the car on the charger. Use a 10 amp charger, not a trickle or maintainer. Next morning, before you start the car, check the battery at the terminals. It must read 12.6 volts or higher. If not, replace it.

Now was to why all of that has a sudden impact on the radio reception, I'm a bit lost there. If you bring the battery up tp snuff, and the radio works, all is well. Otherwise, grab a used one ACM (CD player) outside of the VIN numbers on eBay. fwiw, I have great reception in my garage and as soon as I drive around, it's terrible. Happened when I bought a replacement ACM. Too lazy to fix it. We can walk you through replacing it too. It's not a terrible job. 1 hour if you take your time.

 

Wow!!! Lots to think about and do. You guys obviously know your cars and after owning my Jag for only 7 years, can’t tell you how much I appreciate the help. I’ll let you know when I complete the battery charge, fuse check and other suggestions.
Thanks again,
Jay

 

True enough, @Sean W . As you know, the differences in the electrical charging systems between specific vins is clearly articulated in the workshop manual. It is interesting that my (very early vin, one of the first cars to the amers) xkr ‘s system has not been meddled with: no agm, no maintainer. And she is dependable and operates flawlessly. Even after sitting for a month or two.

As those of us know, at the first sign of a degraded battery (some examples: the infamous parking brake module failure, the centre console does not power up or, the single chime on depressing the start button). just replace the damn battery already. ;-)

We’re coming up to winter… history shows these threads are going to get more action.
Cheers!

 

Great reminder Guy. I have an early XK built in 9/06 and the notice for me when the battery voltage gets low is “cruise control not available.” Amber letters write in the middle of the dash cluster.

Damnations, I forgot one!

I wonder if our cars were stable mates n the way over??
