Well Overall im pretty happy I do like the bigger more clear display but with the X920bt having all the features of the X930bt, the Z140BH here is is all I noticed different:
Overall same look at and feel and speed is identical to x920bt
Screen is much clearer
The app radio (advanced app mode) is pretty much a joke, its buggy slow and pretty much worthless.
Has same aha and pandora interface
Has built in HD radio tuner which is pretty cool. I do notice a difference in clarity.
Regarding connections and cables:
Uses the same power harness so I didn't have to swap that out
Uses the same USB cable as x920bt so didnt have to buy a new one
Uses the same GPS antenna and connection so I didn't have to mess with that
Uses the same MiC
The pioneer pac steering wheel control was identical so no reprogramming just plugged it in to the wired remote.
Bypass is exactly the same as Z130BT move yellow mute cable from bottom to top hole above where it is now. Ground the parking break, new placement of mute wire and ground cable together.
I am let down and disappointed by the following compared to the x920bt
No voice recognition for address and POI
the voice tts prompts for navigation is really bad, the voice is not nearly as smooth and fluid as the unit from 2010, I mean what is up with that? Back to Avic d3 days I guess.
In regards to the maps again it is nice to have some newer updated maps that actually has my house built in 2010. It definitely does want to route me all over the place differently then the older maps. Not sure if thats good or bad just different.
I mean really the advanced app mode, if that's all you get with the app radio its not wonder the scathing reviews, I mean its just awful. I have an iphone 4s. Motionx requires a 25 dollar upgrade fee to use on the appradio?
Anyway that's my initial thoughts, after a few years with the existing x920bt model using it with the 3.0 upgrade there is really no difference other then the advanced app mode and the new navteq maps. No voice address features, so I guess im just happy with the nicer screen I guess. I mean really I didn't use the address entrance features all that much but still it does suck to lose features. I wonder why they removed it.
