Shipped my 536 from Reno on 6/10, back on my desk today 6/26. Works as advertised, looks like both the display and the keypad were replaced.
Bada-Bing, Bada Boom, all is well!
I only have one experience with Unidens repair (BC15XT), & it was just shy of 2 months start to finish. Luckily it was a "spare" radio, but I'd really forgotten about it by the time it finally showed up in the mail.
