I received my 900BT today from Crutchfield which I ordered yesterday (kudos to CF for the quick shipment which was free by the way). I went to Circuit City and had it installed by one of my friends who I used to work with at Circuit City back in the day (he's the only person at CC that I trust installing LOL).
Good news for those with the AT&T Tilt. I remember reading before that this phone has problems pairing with the Pioneer Bluetooth module (as with other PDAs). I had no problems at all pairing with the built in Bluetooth. The only knock I have on the Bluetooth thus far is that when importing my phone book, it lists each number per contact as "General" versus the actual type. So when trying to dial someone by voice command, you have to wait until both numbers appear on screen and tap the one you want to dial. I don't know if this is a issue with the AVIC, phone, or both. I'll have to download the manual to see if there is a fix to this issue.
As far as phone calls, I'm not experiencing the issues that others are having on here. I called my wife and she could hear me just fine. There was a lil echo on her end, but other than that the phone call went well. This was both with the car off and while driving. This was only one phone call so further testing will need to be done to confirm that my unit is clear from those problems that others are experiencing.
I took the micro SD card out of my phone, and using an SD card adapter, inserting it into the SD card slot. The unit separates the media type which I was happy about. When I inserted the card it defaulted to music files. There was a button to access the video files on the card. I thought it would just throw both music and video on there together leaving the user to cycle through. I have about 10 .wmv on this card and the unit played back 2 of them. I was unaware that the unit could even read .wmv files. It played back the .avi files just fine. I'm guessing the 2 .wmv files that did play are using a different codec or something than the ones that didn't play. I wasn't able to figure out how to change the aspect ratio of the videos though (user manual download needed)
I have no issues with the navigation thus far. I tested the accuracy by inputting addresses that I already knew and the unit did what it was suppose to do in getting me there. It does a good job and getting you within a few feet (less than 20) of the destination (I heard stories of previous AVIC units only getting you within 500 feet or so..yikes) I only tried 3 destinations, but so far so good.
I love the fact that you can search POIs by category and name. I also love the fact that when searching for gas stations that you can search by brand of gas first (I'm a Shell guy personally). So guys like me who like to stick with one brand will find this very useful.
There were some rumors that the unit doesn't mute the radio when a navigation voice prompt comes on, but I am not having this issue. It muted just find when the turn by turn voice directions came on.
Speaking of voice directions, I am also experiencing the "comma" like everyone else. But this only occurs when I use the female TTS voice. On the default male voice, he uses "point" (keep in mind that the male voice isn't TTS) Hopefully Pioneer can fix this with an firmware update. If they don't, it's no big deal to me personally. It's a minor annoyance that I can deal with.
After activating MSN Direct, I was disappointed at first that no information was coming in. I live in the Norfolk/Virginia Beach area which is in the coverage area. The information eventually came through. I don't know if this was just a first time use issue or not. My wife and I are going riding later tonight (she wants to see the unit...no not that one....) so I'll check the MSN Direct again to see if the info pops up right away or not. BTW, I know some were having issues with the gas station info not showing up properly. I had no issue with the gas station names popping up, but not all of the gas prices popped up. I think others were experiencing the opposite. I can't say for sure if this is an AVIC issue or MSN issue though.
I don't have an Ipod or a USB device (although I was able to charge my cell phone through the USB cable but the AVIC didn't recognize it as a device) so I can't speak on those.
Overall, I'm happy with the unit. I try not to think about how much I spent on it (I'm a cheapskate) and just try to enjoy it as much as possible.
