I'd have to agree with the last few posts on here. The upgrade on my F90 was super easy!! I have not noticed any better boot up time, but the unit is much faster with the buttons and screen clicks. One interesting thing was that it kept all of my settings! So no issues there.
So far I'd have to say that I'm REALLY impressed with the MSN DIRECT upgrade. I live in the northeast in an area where MSN has always said I have really good coverage, however I've always had horrible reception. After talking with Pioneer initially about it, we blamed it on the fact that I have an etched antenna built into my rear window. I figured what the hell, I get 3 free months...whateva.
But now with the MSN firmware update, I get a strong signal EVERYWHERE! Looks like it really did have to do with the firmware. I think one of the major issues with the previous firmware was that the MSN tuner would not change channel freq's early enough when it was getting bad signal to noise. When looking at the diag screen for the MSN I can see it looking for the best feq to tune into constantly as I'm moving around.
The new traffic flow features on the new maps is also awesome! It already saved me from a traffic jam today! Now only if they can offer the doppler radar!
I know the MSN thing is not a big deal to most people, but coming from Garmin land where I used to use their traffic features, this is a big upgrade to me.
Cheers Pioneer!! This was totally worth 65bucks!
