I got my x50 about 2 months ago, and after the first month i had to send it to escort because i got a service required. They replaced the antenna and recalibrated it. Now, ever since i got it back about 2 weeks ago, its been getting a self cal msg pretty much everytime i turn the car on. Its totally random though. I leave it on and it eventually just restarts and it seems fine. Is there something still wrong with my detector always displaying self cal?
