Turn by Turn directions no voice using Bluetooth

I have an iPhone 4 and Google maps. I have been able to get bluetooth voice to work on my car stereo (2012 VW Passat TDI SE, with the RCD 510, premium 8 radio) - BUT

it is vey erratic. Some times it works flawlessly, inturupting whatever is playing on the radio, other times not. In fact, sometimes just with the the bluetooth connction on for hands-free phonecals, no sound from Google maps!

So frustrating!

All I can say in a very mad way:

(Repeat):

So here we have two giants like Apple and (your car company) and they expect (?) guys like us to resolve their problems! Is that great or what?

Keep trying and keep us posted!

I have found that the turn by turn directions will work on the car radio thru Bluetooth ONLY if my car radio bluetooth is set to "iPod." It does not work at all thru bluetooth when I have the radio on, even though blue tooth works fine for phone calls while I am listening to the radio.

I called Apple about this and they told me it must be my car radio and I should call my car manufacturer because no one else had reported the problem and everyone who complains about it in these discussions is just mistaken. Not the kind of Apple support that used to be provided in the good old days.

If your bluetooth works with other devices proiperly, but only doesn't work with one particular device, then basic logic dictates the problem is with that particular device.

And usually, it's a PEBCAK situation where RTDM will solve the problem.

My iPhone works fine with my car radio in all circumstances (including other iPnone apps) except when using Apple's Maps application. So doesn't your basic logic dictate that the problem is with this particular app? Particularly since the iPhone does work with this device when Maps is not a factor?

Does the Maps App work with other devices? As of this moment, you have one situation where the App & the secondary device are not working together. You need to try a different third-party device, one that is supposed to work properly with the Maps App. Or, you try a different iPhone with the car radio. You need something to compare the base situation to in order to figure out which is causing the problem.

I have not had the opportunity to test my phone with another bluetooth device, but if you read the thread you will find that users who have car radios that support the AD2P profile have found that AppleMaps will interrupt the radio when that profile is being used.

In my case on another thread I found that later Toyotas do support the AD2P profile and that those Toyotas report success with Apple Maps interrupting the radio with turn by turn updates.

Given that with the same iPhone, and the same Toyota, Google Maps does interrupt the radio with turn by turn updates, I would say it is clear that a setting within the software in Apple Maps is the reason that Apple Maps does not interrupt my radio in the way that Google maps does.

I suggest that it is because AppleMaps uses the AD2P profile for turn by turn updates, but Siri uses one of the 2 headset profiles to interrupt the radio. If Apple could allow Apple Maps to use the same profile that it allows Siri to use, the problem would be solved for users whose cars support the headset profile, but not AD2P.

My iPhone 4 works sometime with my 2012 VW Passat (RCD 510 Radio). Yes, turn by turn instructions cutting in over whatever was playing on the car radio. Just sometimes! Othertimes, zilch! Even on the same leg of the same trip!

I changed nothing to get it to work, and I changed nothing to make it stop working!

The voice-over-Siri for Google Maps worked for me ONCE, and then never again, even though nothing in my car or phone changed. It's so frustrating! I have a 2010 Mariner and an iPhone 4s. I play music via a USB drive most often. Nothing. PLUS, there's no sound coming from the phone, so I can't even hear the directions that way. You'd think at least if you had the voice directions running Siri would notify you of upcoming turns through the phone. I've tried every solution I could find, and nothing works.

I have no problem with my 4s and my Ford SYNC. Neither has my wife, with her 4s - with also a Ford SYNC.

I will repeat the steps:

Set your car system to Bluetooth mode

Make sure your 4s has its Bluetooth ON

BTW, have your car system connected with your 4s...it is simple to do, but it takes some steps!

Verify that all of the above have been done.

Plz come back here and tell us how you did!

If everything else fails...turn off the Bluetooth in your 4s...you'll get the voice thru the phone only, but at the same time you'll lose the "hands-free' phone function - not good!

My last free advice: Do not try to set everyhing up while you are driving...park your car, then play with the 4s and the car's system, and I'm sure it will work at the end :-)

BTW, at least with Ford SYNC: It goes back to its default "Line In" when you turn your engine OFF.

So each time you restart your Ford, you have to reset the SYNC to its Bluetooth mode...a real pain!

I have a 2011 Ford F150 with SYNC. I also have a iPhone4 and it has the latest IOS. I use my bluetooth all the time with no problems what-so-ever. I also use Google maps (can't stand Apple's "Maps"). I also like to drive with my window open at least a crack which means I will NOT be able to hear the voice navigation of Google Maps on my iPhone UNLESS I plug it into the usb and SHOULD be able to hear it on the vehicle radio (it is the stereo system that came with the vehicle - bought new). Unfortunately this just doesn't happen!

I have tried turning off the bluetooth and then starting Google maps - no luck.

Most of the time if I get everything set on the iPhone with Google Maps and am ready to head down the road and then plug in the USB the display on SYNC will show me that MY phone is trying to call me!! (my telephone number shows up on the display!).

I cannot for the life of me get my iPhone to give voice navigation through the speakers even though when I connect my wife's Razr everything work beautifully!!

I have questioned my Ford dealership as well as Verizon (my xarrier) and also a couple of Apple stores (their answers are "we don't deal with iPhone problems - WE are an APPLE store". My response, "Do you sell iPhones"? Back to them, "Well, yes". My retort being, "Well then you SHOULD have an answer". .......... Their repsonse............................. a freaking blank stare!

Does ANYONE think I will stay with iPhone when my contract is done?!!

Well, the only question you posed, I would have to answer, that is your decision. As far as the issue with Google maps and connecting to your vehicle, Google maps is a 3rd party application. I would check with their support to see what Bluetooth profile it uses to send the voice navigation. As far as the iPhone 4 is concerned, it does not support voice turn by turn directions, so that is not an option. Being that the Ford truck is a 2011, have you had Ford check to see if there is an update to their software? Since the iPhone supports the latest Bluetooth profiles when they update the iOS, it is very possible the two do not work together now.

I have a 2011 Volkswagen. The bluetooth works fine with the phone, but no voice with Maps. I discovered that by turning on the sound system, turning on some music on the phone, and selecting Bluetooth as the input for the sound system, I get Siri's voice on the turns. If I stop playing the music on the phone, I still get voice. But if I turn the sound system off, then back on again, I have to go through the drill of playing the music, and reselecting the input. Kind of convoluted, but at least it works. IOS7.

Sorry .. I have 2012 plugin prius..with a IPHONE 5 .... SIRI,google maps , Waze and Apple maps bluetooth turn by turn directions worked on Ios 6

.. only SIRI, & Google Maps works now on IOS 7 .. very frustrating ... Any on have same experience ?
