Hi, i have a 2008 hst & iphone 4, the bluetooth was working great, it has stopped working, it connects but when i make or recieve calls it dosent connect to bluetooth

Turn iPhone Bluetooth On:First you want to make sure that Bluetooth is functioning on your iPhone. Click on the Settings icon from the iPhone desktop. From the settings screen click General to show the iPhone General Settings as displayed in the below image. Notice you can see if Bluetooth is on or off from this screen. General Settings screen you can click on Bluetooth to configure the Bluetooth settings. On the Bluetooth screen shown below click to the left of Off to turn Bluetooth On.

1. Begin Uconnect Setup:Now that Bluetooth is operational on the iPhone you can start the Uconnect process. Click the Uconnect button on the rear view mirror to begin. The voice from the Uconnect system will ask you to verbally select one of the options from the menu. Once Uconnect asks for your input say "Setup" to begin the process of syncing the iPhone.
2. Start Phone Pairing:Once you say setup in the above step the Uconnect system will list numerous options available from the setup menu. One of these options is "Phone Pairing" so when the Uconnect system asks for the choices from the setup menu say "Phone Pairing".
3. Pair a Phone:In the Phone Pairing menu you can modify current entries or begin pairing a new phone. After Uconnect lists all of the choices you should say "Pair a Phone" to begin the process of pairing the iPhone.
4. Uconnect Pin Code:The first step in pairing a phone is setting the Bluetooth Pin Code that authorizes that phone to pair with the Uconnect system. When asked for the Pin Code say any four digit combination such as "1 - 2 - 3 - 4". Uconnect will repeat back the Pin Code so you can verify it has recorded properly.
5. Connect iPhone To Uconnect:After you have set the Pin Code for the Uconnect system you need to view the iPhone's Bluetooth Settings screen which you can get to following the steps in Step 1 above. Before the Uconnect system shows up in Bluetooth the Bluetooth Settings screen will look similar to the below where you may have other Bluetooth devices showing or not.After a couple seconds the Uconnect system will display as "Hands Free" as shown in the below image. Notice it states that it is not yet paired,,,,,
6. Click on the Hands Free device showing in the Bluetooth devices list above. This will open a new screen as shown in the below image that prompts you for the Pin Code you specified in Step 5.
   
   Enter the Pin Code and then click the Connect button in the top right corner of the above window. This will pair the iPhone with Uconnect and take you back to the Bluetooth devices screen where the Uconnect Hands Free device will now show Connected as shown in the below image.
   
   After the device is connected you will be prompted by the Uconnect voice again so proceed to the below steps.
7. Phone Name & Priority: After connecting the iPhone you will then name the phone and set a priority between one and seven. Name the phone anything you would like and if this is your primary phone set the priority to one so this phone always connects at a higher priority than any other phone.
8. Verify & Test:Now have a friend dial your cell phone while you are in your car to see if the music volume lowers and the Uconnect voice tells you there is an incoming call from a certain number. To make calls you can press the Uconnect button and follow the voice prompts.
The Uconnect system is a great way to safely use your cell phone in the car.

You will need the dealer to run some special testing.

Hi. Does this happen with other phones too? Is it the first attempt at connecting to an Iphone 4? It sounds like the kit you have is not compatable to the phone. Kind reagrds, Neil

You'll have to confirm this with BMW as we have a 650, 135, and X3 not an X5, but your car won't play iphone based music via bluetooth. It will sync contacts, make calls and some other things (particularly with the newer apps) but it won't play your music.

To play your music you have to have the package that allows you to connect your iphone via an iphone cable (usb at one end, iphone connector at the other - what you use to charge it). With this connected you can then see all your music and control your iphone through the screen on the dashoard.

there are alot of variables for bluetooth. Type of phone, phone service and provider etc... what type of phone are you using here is just one of the latest post from gm.

#PIC5504: Intermittent Bluetooth Issues With Apple IPhone 4 - (Jul 13, 2011)
Subject: Intermittent Bluetooth Issues With Apple iPhone 4 Models: 2008-2011 All GM Passenger Car and Light Duty Trucks with RPO (UPF or UWE)

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:A customer may report of intermittent Bluetooth issues with their Apple iPhone 4.
Recommendation/Instructions:An issue with intermittent Bluetooth disconnects between the iPhone 4 and some GM vehicles has been identified. You may experience no audio in the vehicle for incoming and outgoing calls. When this occurs the Bluetooth system will say "Unable to place call on your Bluetooth phone". GM and Apple engineering groups are currently working on a resolution. The PI and GM Bluetooth website will be updated as soon as more information becomes available.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

You need to make your phone "discoverable" to your bluetooth. Go to settings menu on phone , then wireless and networks. Click on bluetooth settings and click " discoverable mode". The car will never find your phone if your phone is not discoverable. Hope it helps.

Most likely that is a Bluetooth connection. You need a phone capable of Bluetooth connection and it should work automatically. If you have a phone with that capability, but it is turned off, then just turn the Bluetooth in your phone on and you should be good to go. If your call phone is not Bluetooth compatible, and you happen to have a friend with a bluetooth capable phone, have your friend sit in the car and give it a shot -- if the phone button still does not work, then there might be some sort of hard-line that you have to connect, but in a late model car like a 2008, it is more likely that you just need a phone that can talk to the car.

It's not possible to obtain stereo Bluetooth for the 2008 Prius. Toyota did not make this possible until the 2010 model with the navigation package. Actually, if your iPhone 4 is jailbroken, there is a complicated way to trick the car into thinking your music is actually a phone call, and it will force play the music over the speakers as such. But the quality is terrible (mono, not stereo). You're much better off sticking to the AUX cable, even though it does get annoying to plug in every time you drive.

Did you try just pressing enter (no code)? If not, try "0000" I found something here: http://fordfcsd.wunderman.be/UK/Audio%20-%20Multimedia%20-%20Navigation/Bluetooth%20%26%20Voice%20control/bluetooth%20%26%20voice%20control%20%28cg3504en%29%2001-2006.pdf which indicates "0000" is the code, but enter should do it

i use to work for honda and acura and from what i recall, the iphone is and or wasnt compatible with the bluetooth sytems(factory) i was haveing trouble pairing a custs iphone in a pilot, then was told its not compatible with that phone
