My phone connects to the STS system via bluetooth flawlessly, but when I receive a call, sometimes the radio will mute and other times the radio stays on. You can't hear the caller over the radio. You also can't click the mute on the wheel or try to turn the radio off once you accept the call. Neither of these work once the call is active. The radio does mute while the phone is ringing but comes back on after you pick up. The radio always mutes when I initiate the call. I've looked through the car and the phone configuration and haven't found any options pertaining to this. Any idea's? Thanks for the input ...

That seems to be standard equipment on my '07 also.

This is a common problem that has been discussed a lot on here. For me the only way to avoid this was to never answer the phone using the answer button on the nav screen or the answer button on the steering wheel. If I only used the answer button on the cell phone it would work almost all of the time. However, if I ever used the answer button on the nav screen or steering wheel then the answer button on the phone would also stop muting consistently and it would take a while to get back to muting properly. So try only using the answer button on the cell phone for a while.

I recently got the new nav system update that came out a couple months ago. I have tried the nav screen and steering wheel answer buttons a few times and did not have the muting problem. Maybe they fixed it, but I have only tried it a few times because I have become so conditioned to using the answer button on the cell phone.

We had both of our cars (06 STS4 and 06 STS-V) updated, and we still have the same problem. VERY ANNOYING!

I've never thought about trying to answer with the phone since it's usually in my pocket. I'll have to try that.

There really need to fix this. It is SO irritating.

Thanks for the input... I will give it a try... I never considered using my phone to answer the call... Now that you say it, I almost always use my cell phone on out going calls (because the car is moving and the STS lock's out the dial pad) and I don't encounter the problem. Cool .... Thanks ....

This is my biggest problem with the car. I'm a sales guy, and need to be on the phone all the time to make a living. The most irritating issue is that it will work perfectly 9 out of 10 times, then when a vp that you are trying to close a major piece of business calls you, you try to pick up and all he hears is some "colorful" music cranking on XM. Not good. Embarrassing. I now turn the BT off on my Treo when I get in the Caddie.

I'm literally driving my loaded Jeep Commander more just because the bluetooth works flawlessly!

Had this problem a lot with the 2005 but was reminded of it with this thread and just went out and tried it in the 2008. Seemed to mute OK. Hope it is not an intermittent problem that I just haven't come across yet. It certainly was a nuisance, especially since once the call was answered the volume and on/off control of the radio was disengaged.

It is an intermittent problem, assume it would still be the same with an '08 since I believe it is still the same equipment

I had the same problem with my 06 STS and Samsung A900 phone. I also have a Mazda CX-9, and had some Bluetooth issue with it too. Mazda has a dedicated customer service section for Bluetooth issues, so I spoke to them, and they told me to upgrade the software in the phone after I told them what version it was. I took the phone to my local Sprint store, they upgraded the software, and BINGO--no more Bluetooth issues in the STS or CX-9.

So, I suggest checking to see if there is a software update for your cell phone.

Sad that Mazda provides much better Bluetooth support than Cadillac!

I recently swapped the A900 for a Palm Centro and it works perfectly with both vehicles--no issues.

I had the same problem. It went away when I updated my cell phone os.

i have also found this to be true with many many phones. the motorola v55x series was one of the worst. most likely the problem is with the phone.

so far i'm having good luck with the v3x or vxx's. i personally have the v9 connected now, and it too has a small quirk...the tone for when you receive a message seems to not want to play when connected.

You might want to try one of the web sites that feature cell phone blue tooth / firware upgrades. update the ROM on your phone and see if it helps. Did for me.

great another problem that can drive u up the wall. Cadillac needs to get their act together. This happens to me too, so what i do is Press "AUX", Hit "Private" then turn the radio OFF and the Press "Hands Free"......but really for a $$67,000 car should i be doing all that?????
im going to take my Voyager to Verizon and see if there is some sort of update. see what happens

I'm not sure what you mean, but when a call comes in, and the nav is aware of it, all "soft" controls are locked out except for the volume knob. So, you will not have a chance to press the AUX button, etc. Even the mute is locked out. The only controls that seem to be available are the screen buttons, ONLY in the screen you were in BEFORE the call can in.

Try dialing *228. This is the programming for Verizon. If there is a new firmware, it will load automatically. Don't bet on this fixing the issue. When I listen to a CD I always stay in the CD screen so if a call comes in I can quickly push the pause || button. Unfortunately, for no apparent random reason, it can take many seconds between the phone answer button activating, and the screen changing back to the CD screen to the pause soft button activating. This means the caller get an earful of very loud music (usually Megadeth and the like). Ironically, when I first got the car before any software updates to the nav, it worked perfectly. After the updates, it stinks and only mutes when listening to the radio, which I rarely do.

Don't get too down on the car. It's still a great vehicle, but the little technical glitches WILL drive you nuts unless you find a way to live with them.

jgrade is not the first person i've heard say this either. mine has been upgraded, and i've never had these issues though.

Funny.. My Voyager always worked perfect with the STS until I got the latest update for my phone... Now the mute issues happens atleast one time a day...

Thanks for the input... I performed the upgrade on my phone just as you recommended... I just did a test of 15 calls, it connected properly 14 times... That's much better then what I had before... The car goes into the dealer on Thursday... Certified car, so no charge to me and they will upgrade the software in the car... I am also trying to get an updated NAV DVD disc.

good to see it worked out. hope you don't have more issues after upgrade.

Well it's back... I am back to about a 50% mute ratio on in coming calls and it works 100% of the time on out going calls. The Cadillac dealer said that he wasn't aware of any problems and I informed him that I have learned from this forum that many people have experienced the problem. My daughter just bought a Blackberry, so I guess I will try her phone for a while and if that works, I'll get a new phone. I'll let you know what happens.

I have had that with my Treo 700p as well. If you already have the latest software, try rebooting your phone. Usually, that gets mine working again.

Same issue here. Verizon customer with LG BT phone. My quick fix sequence is a little different. when call received, i press answer icon on screen. If radio does not mute, quickly hit AUX, then PRIVATE, then HANDS-FREE. I don't have to turn the radio off. For whatever reason, this works. When call completes, radio/cd plays. But I agree this is unacceptable for 60k vehicle. Will mention to dealer next visit.

With the four phones that I have tried, I have found that it is better to never answer the phone using that button on the screen. Then I don't have to do the rush to private as I run off the road. I just keep my phone in one of the cup holders and use the answer button on the phone. If you ever push that button on the screen, it seems to remember and causes problems for the next few calls.

If radio does not mute, quickly hit AUX, then PRIVATE, then HANDS-FREE.

...and tap the sunroof three times while making a barking noise...

this nav is rediculous...

and don't forget to stick your left index finger in your right eye at the same time!!!!

Using Verizon 9m, no problems, except a loud sort of low pitched "beep" when I press voice mail a couple of times.

I have an STS 05 and use to have a TREO that had the intermittent mute problem. When I switch to the Blackberry the problem totally disappeared and I've had it for about a 6 months.

Another issue I've noticed ... if you use remote start and not near the car for more than about 10 seconds you have to manually connect the Bluetooth. The phone will not automatically connect ... happens with my TREO and the Blackberry.

yeah, the phone has to be in range when vehicle starts to sync up, which excludes remote starts from distance. but if you're close (who would be though), it syncs up.

I now have discovered that the phone mute's properly when the source is FM, it appears to be a problem only when in XM. It is at the dealer as I am writing this for that problem and the recall on the seal in the differential. I'll let you know what the dealer has to say about the problem.

Hey, consider yourself lucky! My Bluetooth doesn't work at all. And the voice recognition system isn't a heckuva lot better. Oh, what the heck, they only costs me several thousand dollars. My first GM car and my last. Unfortunately, it's only two weeks into a three-year lease.

It won't work on CD either. Forget the dealer, they will tell you that your phone is not certified and there is nothing they can do. Trust me I have been there MANY times before.

There are some pretty smart poeple here that may be able to help. Give us a description of the issues. For the VC, the only advice I can offer is to not have the blower on the climate control set to defog or higher than low. Other wise you need to exaggerate each syllable (or add syllables) of the word you are trying to pronounce. I.E. Try saying "navigation grow-cer-er-re store with a long o and hard e to pronounce grocery store or it will not understand you.
