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) Was the device turned OFF "manually" - the last time it was removed from the vehicle?
2) Can you try pushing and HOLDING (for up to 45 seconds) the power switch - WITHOUT connecting the device to any power source - and see if the screen comes ON?
Please use the REPLY box below.
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)
