Does you radio lose its presets for FM and SAT?

 

Check your battery condition, terminal connections (for tightness), and check the voltage--both at rest, and at cranking (shouldn't drop below 8.5v or somewhere in that range*). If the battery is getting old/weak it can dip below a certain voltage, and the infotainment system can fail to load presets. Happened in my former Jag, and it's something simple to check first before reaching for your wallet at your dealership.

Hope this helps!

*I'll have a look to find the exact threshold, unless anyone else has that info handy.

 

No, it has nothing to do with the battery. I have this problem upon occasion. I don't use the over the air radio, but it definitely happens with the Sat presets. And it's inconsistent. Sometimes it happens just when I shut the car off, go into a meeting, and come back out. Sometimes it happens after the car has sat for a week. I tried to have the local dealer do a search on it to see if there's anything showing up, but nothing came back from my first try. This is the only gremlin I've had show up, but I've not found it reproduce-able enough to take and leave with the dealer yet...

 

I had been running on the suspicion that it had something to do with not getting signal from the satellite after turning on. But if that's happening for the am/fm stuff too, that may not be a valid theory.

 

Yet a third thought with a third post... I've started locking the car when it's in the garage, and haven't seen this gremlin in about 6 weeks. <shrugs> Maybe it IS the battery and the electronics are just really sensitive to even a moderate drop in voltage.

 

Happens with both AM/FM and SAT

 

Jaguar Special Service Notice #SSM42465 (dated 10/19/09) is the similar wording to the Jaguar SSM I found back in 2007 to diagnose a similar issue with my X-type. So, I'm merely relaying the info...

Actual text from the factory notice:

Cause:
When the vehicle system voltage is below 8.5 Volts at the SDARS unit under cranking conditions, the Satellite Radio is unable to transmit over MOST the 'User Presets' to the HLDF (High Level Front Display) causing either loss of presets or some presets to be missing.
Action:
If a customer complains of 'Loss of Presets', check battery condition and charging system. Do not replace Satellite Radio units for 'Loss of Presets'. Reset the customer's presets and advise customer of selecting Satellite Radio prior to starting the vehicle.
Note:
If the customer selects the ignition on with Satellite Radio playing prior to cranking the vehicle, 'Loss of presets' should not occur. A service fix will be made available as soon as possible.

Good luck!

Same here.

 

Ooo, EMX -- that's useful, thanks. <thinks> Do you remember what the permanent fix was? Other than to turn on the radio prior to cranking the car? <chuckle, what an interesting fix>

 

Theres a bulletin to reflash the sdars/sat and that fixes it

 

Ok, so my presets for Sirius were gone. I re-entered new stations and I lost them. A couple of weeks later, I get my presets from two resets ago! Very odd, I would’ve thought if any presets came back it would be the last ones I did, not two back…

 

So, the Sat presets have already disappeared on my 2013 XK. Not only that, there are other strange things happening with the Sat radio. On two different occasions, I couldn't change the channel. No matter what I would do, the same channel kept playing. Then, to make things even more weird, sometimes the Sat radio will never turn off! Even when I turn the car off, the damn thing keeps playing. The only way to kill it is to select another source (AM/FM/ or iPod.) I don't intend to subscribe after the 3 months trial runs up, so I'm not going to bother making a special trip to the dealer about it.

 

Yesterday, the presets from a month show up. So friggin odd. You'd figure whatever is currently set as presets is what should remain, not 4 revisions earlier...

 

Well, it turns out that I didn't lose my presets afterall. I discovered this morning that there are 3 pages of Sat presets. If you hit the mode button on the steering wheel, or hit the source button on the center stack, it steps through all 3 pages. In my case, I must have hit one of those buttons and caused the Sat radio to move to another preset page...which had never been programmed, so it made it appear as if all the presets had disappeared. The only thing I haven't figured out yet is how to step through the pages backwards. As it stands now, if I'm on Sat page 3 and want to go to page 1, I have to hit AM/FM, and step forward from there.

 

Wow so maybe they are all there and it's not flaky? Will have to step through them as you mentioned and make adjustments!

 

It appears that the only thing that was flakey was ME!! :-)

Still, though, there is no mention of these 3 Sat preset pages anywhere in the manual. I discovered it by accident.

 

Well, only the presets from Sat 2 and 3 disappear for me. The ones for Sat 1 seem to stay no matter what.
