Question about Kenwood KDC-BT838U Car CD Player

2 Answers

Hands free phone stopped working

Out of the blue today, my hands free phone won't work in my car stereo. The phone's Bluetooth menu shows that it's connected to the Kenwood, but the Kenwood won't read it. I tried reregistering the phone and it says that the device is full (I've only paired the one phone Env-2). When I try to delete the device to reregister, it shows no device to delete. I've had the stereo for months and it's worked great. Nothing happened, there were no changes to the car, the stereo or the phone. Today it just ceased to function properly. Help please.

    Identical to the one described at the start of the thread. The head unit mysteriously lost all its pairings, won't register new devices ('Device Full') and shows no devices to delete. Have not found a solution.

    I have the same problem.  I've only had it for a week.  I hope someone can help.

    Thanks 'wavereel'! The reset button worked like a charm. Redoing the date, time and preferences is a small inconvenience compared to losing my beloved hands free phone mode. You've made my day.

When I had this problem, I just held down the reset button on the face underneath the volume knob (look in the manual if you can't find it).  It erased all of my visualization preferences, date, and time settings, but kept everything else and now my bluetooth works again.  I hope this isn't something that happens often, cause it will get annoying to constantly be resetting the date/time and other stuff.

How do I pair my phone to my blue tooth


Connecting a Bluetooth headset or car kit You can listen to music over a Bluetooth stereo headset, or have hands-free conversations using a compatible Bluetooth headset or car kit. It's the same procedure to set up stereo audio and hands-free.
  • For you to listen to music with your headset or car kit, the headset or car kit must support the A2DP Bluetooth profile.
  • Before you connect your headset, you need to make it discoverable so your phone can find it. You can find out how to do this by referring to your headset manual.
  1. From the Home screen, press MENU, and then tap Settings > Wireless & networks.
  2. Tap Bluetooth settings.
  3. If the Bluetooth check box is not selected, select it to turn Bluetooth on.
  4. Make sure that the headset is discoverable.
  5. Tap Scan for devices. Your phone will start to scan for Bluetooth devices within range.
  6. When you see the name of your headset displayed in the Bluetooth devices section, tap the name. Your phone then automatically tries to pair with the headset.
  7. If automatic pairing fails, enter the passcode supplied with your headset.
The pairing and connection status is displayed below the hands-free headset or car kit name in the Bluetooth devices section. When the Bluetooth headset or car kit is connected to your phone, the Bluetooth connected icon is displayed in the status bar. Depending on the type of headset or car kit you have connected, you can then start using the headset or car kit to listen to music and/or make and receive phone calls.

I have got a Jabra BT620s and connected it with usb to Windows 7 64 bit pc. The drivers automaticly were installed and ready to use. But there is no sound trough the headset, only trough the speakers. When...


Does your computer have built in bluetooth? if yes,make sure you press and hold the stereo bluetooth till its steady blue,,not blinking blue. then on your pc, go the bluetooth section in control panel and search for devices. then you should see the Jabra Audio device.click on it to connect to the Jabra and use the passcode 0000. After it connects, the steady blue should now be blinking blue. Then go to control panel, sound and you should see the Jabra there.Right click on it and click on set as default device. Now play any song and see if you still have it playing in your speakers.Let me know if it works.I have the same Jabra and its really works great.Especially when im working out and dont want no wires around me

I have ck-7w bluetooth hands free kit in my car been working fine till today now not working


the kits commonly lock up, you will need to remove power from the main junction box behind the dash, this will power down the kit and reset, then hold down the nokia button till it bleeps and try pairing your phone again.

I want to hook up my phone to car stereo as an auxilary and need a cord that fits phone that will plug into 3.5 jack. any suggestions?


Pick up a corded hands free device, providing the 3.5 jack is for the car, and there is one that looks like the 3.5 but is smaller for the phone. If your phone has one of those "data" looking plugs for the hands free, this will probably not work.

Then go to radio shack and buy the parts for a 3.5 plug, the friendly geeks there should be able to direct you on its reasonably simple assembly. Simply cut the headphone/mic, off of the hands free, attach your 3.5 and Bob's your uncle!!!

Too complex?? You could also try the "Jupiter Jack" as hawked by Billy Mays. It will broadcast your phone to your car with radio waves.

Hope this helps!!

CK-7w mutes stereo


if cutting the power to the kit dont work try removing the radio and removing the yellow wire from the back for the radio (the one coming from the junction box of the kit). that should get the radio/cd working properly. inspect the wire and make sure its not earthing anywhere behind the dash. radio isnt realy that easy to take out if you dont know what your doing.

How many `paired devices` have you got in your connectivity settings.
Delete them all and search for a new device e.g: your bluetooth headset.
