Hi all,
I finally have the option to upgrade my stock HU in my car and I am going with one of the AVIC NEX HUs - but going crazy trying to decide which one.
Main sticking point is the nav capability. I've never had a car with built-in Nav and usually depend on my iPhone + Maps but I like the idea of the built-in approach for safety/distraction concerns.
Are folks with the 5000-6000-7000-8000 models satisfied with the Nav systems? It seems from reading the forums that there were some early concerns - are owners more satisfied now?
Appreciate the input as the price differential with the 4000 is substantial.
I have Pandora and iPhone integration questions, but will save those for when I pick a HU. 
Thanks - really looking forward to a NEX.

I've had the Nex 8000 since the first week it came out and available, I will have to say I wouldn't go with any of the other models cause I love the screen, you can look up posts by me to see how I feel about most of the functions.
Pros
Screen is bright and I love it
Sound quality is awesome
Features are great, and with carplay will make me very happy
SD card video and audio is awesome
Pandora, aha work well
Cons
Nav is ok at best, probably about 4k miles used already and I don't like a lot of the routes it takes me and I've tried all the different route types.
USB connection is cool but needs some better options for both USB connections.
Apps for me I don't use em except waze but don't like the smaller screen
To sum it up though, I LOVE IT.
Feature rich, and promise too
