Hello & Welcome,
Sorry I didn't see your question earlier and to hear of any issue you are having with your device.
To help you with this issue, may I ask:
1) The FULL Model Number of the device you are working with? That is, do you have ANY "letters" after the NUMBER - such as LMT or LMTHD?
2) Have you installed the device IN the vehicle yet, using the Vehicle Power adapter that came with it? If so, HOW LONG has the device been running?
3) Are you currently in the Los Angeles area?
May I ask if you have already returned the unit, or just thinking about it?
I only ask because there may be something we can do to get you started with this unit (which is a nice device).
