I am new to HD radio, but I live in a pretty populated area and mine never keeps its signal for more then 10 seconds or so, it keeps switching back and for from HD to non-HD. Does anyone else have this problem? is it normal? also, why is there two HD stations for a lot of channels? thanks for any help

I have the same issues. I don't know what HD is my ATS can never seem to lock on to the station in HD; maybe this can be fixed in a CUE update.

I was with the CUE team yesterday and brought this issue to their attention.

The problem is not CUE. The problem is the HD signal, which is not as strong as AM tower signals and are prone to transmission problems when being bounced off nearby buildings.

Some stations are combatting this problem by installing repeaters to increase signal strength, but I would not anticipate many are actually doing it.

In Minneapols we have about 12 HD radio stations. 2 are on AM and the rest are on FM. I've had no problems at all. After a few seconds the radio switches to the digital version of the broadcast. The FM stations have additional programs on sub channels. For example, there is 92.5-1, 92.5-2 and 92.5-3. I suggest you go to your dealer and test another car radio that is outside and see what results you get. If you are listening to local stations and you are having these problems it could be your radio. The best way to tell is to try another car with an HD Radio.

I'm having this issue as well. The station changes from HD to regular all the time. Also my CUE only finds one station in HD that I listen to. I understand that it's a "signal" issue but it sure is funny that my 07 Tahoe with a isimple HD module and my SONY in my work van not only pickup more stations that I listen to but they don't drop signal like the CUE does.

Now for the real problem. It loses signal so much that I turn off the HD FUNCTION in the menu so I can listen to the station and the damn CUE reverts back to HD. Talk about annoying

Ewired, there must be something wrong with the radio in your ATS. Especially considering that your other radios with HD work. You should have the dealer look at it and fix it. My XTS and my wife's SRX have no problems with HD stations. In fact I can pickup AM stations from from other states even during the day. At night I can pick up WBBM AM in Chicago, two states away, and sometimes it get a strong enough signal to switch to HD, I never have problems with HD staying locked on AM or FM stations.

I haven't looked at how the antenna on the back window is connected, but once on my DTS I noticed radio reception was suddenly bad and upon looking at the connector on the back window I found that it had gotten disconnected and I snapped it back on. This probably happened at a car wash. Anyway, if anyone has bad reception on your radio, have the dealer check it. Prove the problem by comparing reception on another car at the dealer that is outside the showroom.

I am impressed with the sensitivity of the radio in these cars.

My daughter's Ford focus doesn't suffer from these signal issues like my ATS. My HD radio can take up to 20 seconds to connect with an HD station and then cuts out consistently. Rather than just dropping back to analog, it goes totally silent. The dealer called me
today to tell me it's a common issue with GM radios and there isn't a fix. I've switched to using mostly Pandora because it's just too painful listen to stations dropping all the time.

At least my HD radio in my 2013 SRX goes back to analog instead of going silent.

But in general, I am very unhappy with CUE. It will be the ultimate reason why I will leave Cadillac once my lease is up next year.

I have a 2015 SRX and have had it back to two different Cadillac dealers because of the horrible radio reception. The HD goes in and out constantly! The regular FM station reception is so weak, that I can hardly even use the radio. Both dealers told me they're having no complaints about the radio reception from other customers, and there is no problem with my radio reception when they test it. The radio reception in my 2006 Cadillac STS is very good, so they've done something to the design of these radios over the past few years that has destroyed the reception qualities. Anybody else out there having the same complaints?

How did they test to confirm there was no problem?

Perhaps try this: while tuned to an HD station, select the MENU function (far right icon in mine) and turn the HD SWITCHING to OFF. See if this makes a difference.

Have the same problem. Very annoying!!!!!!!!!

The problem really boils down to the pathetic in glass antenna. It not only doesn't provide a strong signal it is also directional. Here in the SF Bay Area, the hills tend to block signals rendering not only HD radio but FM radio in general useless at times with an in glass antenna. The old chrome stick antenna may not have been pretty but it worked. The main reason is because it was a lot longer and being truly vertically mounted helped as well.

I agree that the reception on my 2013 ATS is pretty poor, in general... that causes all stations to come in rather poorly. I'm comparing this to my recently-traded-in Subaru Legacy which had great reception (and a glass antenna) so it's not just the antenna that's the problem, but the overall receiver setup on this car. A signal booster might help on this car... I may have to consider that in the future... but bottom line, reception is poor on this car. I'd suggest turning off the HD if the OP is switching in and out all the time... that can get annoying for sure!

I plan to bring this up at my next/first visit to the dealer... because it shouldn't have this bad a reception... maybe there's a loose connector or something.

You clearly have a radio problem. But as a ham radio operator, I know a lot about antennas. For a FM antenna ideally, you want it close to 3ft long and vertical. Longer doesn't degrade the signal much but shorter does. Deviate from vertical like when it's in a slanted rear window and the signal degrades. The car itself can tend to block signals. The hills in the bay area exacerbate the problem, and for most people the problem isn't FM but the HD multiplex signal that needs to be strong to decode and in glass antennas don't help the situation.

Not sure how I'm going to "prove" this during the dealer visit. Maybe I can sit in a newer one and see how the more-distant stations come in, and use that as a comparison point. If you have ideas, I'd love to hear them.

I realize glass antennas aren't always great, but again, I have had them in many of my cars and they have been just fine (my ancient 81 Buick had them and worked fine too). Again, my just-traded-in Legacy had one and was far better than the ATS's. I'd be happy if it worked as well as the Legacy's did... but in the end, I don't feel glass antennas are "always" awful. They certainly can be bad, but I haven't really experienced a "bad" one yet. As an engineer, I can appreciate the better-design of a whip antenna, but in the end if it works well enough, then I really don't care about "better"... I'm not looking for far-away reception, but I do expect a station about 20-miles away to come in reasonably well.

Again, I'm not disputing your statement - I can appreciate the desire for proper design, but in my experience glass antennas can be "good enough"... and my car simply may have an issue.
