I currently have a Passport 8500 x50 that I barely use during my daily commute on 101 or 280 from/to San Francisco and Silicon Valley. I don't use it much because there are a lot of false signals and, in part because I have to constantly take it out of the car. I can past the latter part but the former has resulted in ignoring it much of the time.
I'm not, if it's not obvious, an expert at all in how to listen/read it and I'd prefer not to be.
So, I've been considering whether I should move to an installed product like the SRX/SR7 or go with, perhaps, the new 9500i with the lockout.
I'd love to hear informed opinions on this, especially by anyone travelling those roads day in and day out.
