The bluetooth headset may not be compatible for the GPS reciever.. Check for the configurations for bluetooth.. and then install..

When you format the SD card try setting it to Fat 32, or Just file see if that helps You.

first check the volume to be on ..and razed...if this seam not to be the issue ..get into the av menu ..and select sound ..and in there check the out-put ...and select the out-puts in use..
The volume you should select it on the screen and raze it ..not with the remote...
If all these seam to be in order..but you have no sound..you should check the speakers wires to be plugged in ok ..and have no damages..
In the end you can make a reset to factory settings ..and default all ..If it does not have it in the menu ...select the initial settings ..when you first open it ..(probably have to be disconnected to display this menu ..)
I will link the manual for it here ..and you can check it for any other questions ..

Connect the parking break as recommended. Then check whether the video appears when parked. If not, send it for service. If yes, then the bipass was not done correctly.

You will nee a KS-U20 Lead from JVC to make videos work.
Then use the AV to view them.
