I have a Whistler Pro 78 that I bought new back in 2007 or 2008. I haven't used it much over the past year or so, but I recently took it out of storage and am about to start using it again. Does performance fade over time, or is there any need to send it in? It appears to be working fine-I've never had a problem with this detector and have no reason to believe it isn't working well, but just curious if there were any updates or anything. I have it on rev. C firmware.
Thanks for your help.
