Hello & Welcome to Just Answer,
Sorry to hear of any issue you are having with your device.
To help you with this issue, may I ask:
1) WHEN was this device last used SUCCESSFULLY (if ever)?
2) The AGE of the device?
3) WHERE has this device been used (in vehicle, outside a vehicle, indoors)?
I see it has been a few days and I haven't seen a response on this page, so I just wanted to follow up to see if you have any more questions concerning this issue OR if the issue was resolved?
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
