Just got a used x50
and I found out it's broken.
I tested it out right at the spot and it worked fine.
But when I tried at home, it would go crazy and pick up 2 Ka bands like there's no tomorrow.
It won't stop even after I reset it.
It's a ver 6.1 and I heard you can get free flash upgrade to ver 6.3 from Passport. But without receipt, I do not know if this is possible.
Also, mine's 0407 so it hasn't been one year yet. But again, I do not have original receipt.
What should I do?
Call up Escort. Assuming the unit isn't reported stolen, its still under warranty. Tell then you bought it via a private sale, I can't see any reason why they won't help you.
