If it's always been like that then maybe that's just how it is, however if you changed something...

It would be nice to use punctuation marks from time to time, as well as the <enter> or <return> key to start a new line.
That way, your post would be readable.

Sorry Nabi im new to all this.... this was my question......Hi guys i have a chinese 4.3 gps and when recieving calls through bluetooth sound is ok but when making calls im getting an echo on the sound its from the unit also i cant seem to link up with the FM speakers in the car anyone have any ideas whats happening. The other info in first post is the specs for the unit i just cut and pasted thx for your help.

From the specs (difficult to read) I see no mention of "FM Transmitter" function on the device. Therefore, except for a physical connection (headphone out on device to line input on car stereo), there is no reason to believe that the device could use the car stereo speakers.
Unless I missed it in the massive run-on sentence/paragraph.

Hi,Yurbuh Tuggly it seems its not showing in the specs but it is definatly on the device in settings...... do you know if i have to set them both at a certain channel for them to link up ......you will have to excuse me im a novice to all this not very tech. thanks Tony.

Yes. On the device, in the FM settings (wherever that is), you set the broadcast frequency...best to use one that is static only and not close to the frequency of a radio station. Then set the FM Transmitter to "active" (however you do that on the device..it is separate from any settings in the navigation software)...this usually silences the device output speaker.
Then tune your car stereo to the same frequency. If set correctly, sound from the device will come through your car speakers.
