Why does my Dual GPS say no signal?
A red GPS icon indicates the unit isn't receiving a GPS signal. This can happen if the GPS antenna isn't connected properly, so check the GPS antenna connection. It could also be due to a damaged antenna cable; inspect the cable for any pinches or cuts. Finally, the GPS signal might be blocked, like inside a tunnel or garage. Ensure the antenna has a clear view of the horizon.
What to do if Dual GPS unit will not turn on?
If your Dual GPS unit isn't powering on, the red wire might not be connected or have the correct voltage; check the connections for proper voltage (11~16VDC). Also, the black wire might not be connected to ground, so verify that connection. A blown fuse could also be the culprit, so try replacing the fuse. Finally, check the 13 pin cable connections to ensure there is a connection to the Dual head unit.
What to do if my Dual GPS unit blows fuses?
If your Dual GPS unit keeps blowing fuses, the red wire might be touching the chassis ground; check for any pinched wires. It's also possible that the fuse has an incorrect rating, so use a fuse with the correct rating.
How to fix no sound on Dual GPS unit?
If your Dual GPS unit has power but no sound, the confirmation speaker might not be connected; check the connections at the speaker. Also, the RCA audio output might not be connected, so check the RCA audio connections. If voice guidance is turned off, go to the Preferences menu to turn it on. In case of XDV8125, if the left front speaker is not connected, select all channels.
