Summary: I bought as an upgrade for my stock radio on my 2004 GMC Envoy. I am please with the unit how easy you can get around the touch screen very responsive from the gps to radio and the phone. I didn't like that it did not have voice command and a removable face to protect my unit.
Summary: I purchased an F900BT with my new truck purchase. The unit failed and had to be replaced three times. Recently, I ordered a 2012 map update for $120. The update failed in mid process and Pioneer charged me $80 to reset the software. After the update was completed I was looking forward to the 12 million POI's they advertised only to find they removed all but a few, ie no restaurants, gas stations, ... Which renders the unit non-functional.
Summary: I got free used Avic-F900bt last year and installed in my Subaru Impreza 2 months ago, the radio is decnt, and I admit its pretty neat having a touch screen for the radio controls. This past week I finally got a Antenna for the GPS and a mic for the Bluetooth. First lets start with the GPS, its quick when you miss a turn, and is pretty good anouncing the turn comming up, but it sucks when it comes to be user friendly, the Magellan Maestro I used to have ( I sliped on ice...
Summary: The only thing I don't like about this thing is that it does not run on android or ios. Seriously, these companies need to stop making touchscreen devices without consulting a true touch os company. Navigation maps are not easy to use on this $700 monster, but an iPod touch from 2 years ago scream for $300, which includes the tom-tom app.
Summary: Fortunately they only made these units for a short period of time. I had always been a big Pioneer fan until this piece of garbage which turned into a waste of a thousand bucks. From the get go this thing gave me problems. The load up time is long. The touch screen is terrible. The screen would occasionally freeze. Then this puppy just gave out. Right out of warranty the unit started powering up and down constantly whenever the car moved.
Summary: This deck is worth every penny I paid for it. It is a little slow on startup, but makes up for that with the beautiful and easy to navigate interface. My friend has the Clarion NZ-409 (same as the NX-409) and the interface and features are plain and boring. You couldn't ask for more features on this unit with the built in Bluetooth, sleek design, voice commands, DVD playback, and Navigation.
Summary: The Pionner AVIC f900BT delivers. Installation is pretty straight forward and easy. The system does everything you expect and want. The only downside is the FN Tuner. While it functions well, it does not have scrolling text that some stations prodcast on traditional local stations. Aside from that everything is top notch! The updates to the Navigation system make this top notch! The GPS and the iPOD setup is nothing short of fantastic.
