Hi on the bose website it says- No, the Bluetooth mobile phone connectivity is for communications only. so using it on tablets and such would not be compatible. Thanks

Use your computer speaker as the sound device or use a headphones.

If it sounds good, it could just be your cable that goes to the receiver.

( using a Y cable to connect to one of the regular audio inputs.)

or have one like these:

3.5MM To Stereo Rca Cables: Electronics

The Digital Rights Management system is blocking your system. This can be a tricky thing to sort out. We need to know what music downloads are blocked - just some or all? What player are you using - iTunes and MS Media player are very active on DRM - Media Monkey is a bit less fussy - you might try it on your computer. Are the files playable on your other equipment. The more info we have the easier it is for us to try and help.

nokia 6300 you have to reinstall the bluetooth device in the nokia servies center.and then you can receive dates from other phones.[or] copy the datas to pc and formet the memorycard........

transfer music to your phone
Before you copy files to your phone, make sure
the files are in a format that the phone recognizes. Your
phone’s music player can play the following types of
audio files: AAC, AAC+, MP3.
To prepare your phone to receive music files:
1 Insert a memory card into your phone (see
page 11).
2 Set your phone to Mass Storage mode by going to - >Settings > USB > Mass Storage.

You should be set. I was having the same problem

I'm having this same exact problem! I purchased a 2GB Micro SD card for my SciPhone i68+, and can transfer music to the card, but it won't recognize it on the phone.

It's frustrating! Any help would be appreciated! Thank yoU!

Place all mp3's in a folder named mp3
