TStevens is correct in the cause. However, you might be able to improve things by repositioning the microphone, if possible. Position it as close as you can to your mouth, and make sure it's not pointing at the speakers. Also, if you can turn the volume down and still hear the other person that could help too.
A better solution might be to get an in-ear bluetooth device (e.g. Plantronics Explorer 50). In general they tend to be better than car systems, and are pretty cheap (from around £15/$20).

Its like calling into a radio station going on the air, and having your radio turned up while on the air you will always get an echo. Or at least a delay that other people will hear on their radio. it's the same way, with using a Car Bluetooth because they are hearing their voice coming through the speakers and going back into the microphone and then they hear that and there is your Echo. Unfortunately there is really nothing you can do except for ask them to deal with it :-(

SOURCE: Cant Pair my Motorola H500 to my LG Rumor

turn bluetooth on your phone on. then on your bluetooth headset hold the power button for about 10 seconds or until you see the bluelight on steady. next on your phone in the bluetooth section klick ok on the search for device option, when you found the bluetooth with your phone it will ask if you want to use that device, klick yes, and it might ask you for a code, enter four zeros "0000" and that should connect automatic.

I would like to take some pictrures off my old Motorola phone, it is unlock, i can scrole through the the pictures but can not download to computer.


Claude, by any chance do you know the model name of your phone?
As someone already answered, the best way is to have the phone connected via a USB cable to your PC/Mac and just drag/dropp the pictures in the desired folder, did your phone came with one?
