Pros I liked the fact this is cheapest major brand Nav and Bluetooth unit. Looks neat and clean and starts instantly. It has detachable screen so you can plan your route.
It also can control iPhone/iPod and USB drive, and audio quality is ok to good.
Cons 1. Bluetooth hangs and daily basis, and only way to get it working is by hard resetting unit, at which point you loose all your setting, Nav, Audio, Radio, bluetooth settings, and you start from scratch again.
2. Nav also freezes- incorrect location
Summary This has been frustating experience with this head unit since I bought it. Bluetooth MIC was useless as other party can not here. So replaced with Garmin Microphone and that solved the issue.
Initially Bluetooth freezing, onlyway is hard reset.
Then Nav started freezing randomly. It fly me thru some unknown areas(with full GPS signal as per unit) far away from where I am driving. The TTS is useless as it gives incorrect directions, sometime forgets to do so.
Major Roads, that are laid 5 years ago does not show up. insist on driving on walking trails.
POIs are joke, you do not have Restaurants, or gas stations, but have Cemetary!!?
Pioneer claims there are no issue reported, where as avic411.com forums says otherwise. Units sent to warranty repair came back with same firmware, and has same issues, and nothing solved. So, no use of repair.
In the end you all be warned, it is upto you to experience all this mess, or avoid like any wise person would do.
Color Display Custumization, DOES WORK.
Excellent if you plan on keeping stock speakers
Cons A bit Complex Menu, takes some time to get used to.
Summary Although this CNET reviews says setting for illumination did not work, they didn't complete the process for changing the color display. After creating a color, saving it to the SD card, copying the settings to the radio, press and hold SRC button until all sound comes off, then press the volume knob for a few seconds and initial settings will appear, select illumination color, change from SCAN to CUSTOM. Thats it works like a charm. Read the manual Antuan!!!
Pros Still trying to find some (price I would guess)
Cons Constant battery problem
Useless contact and POI
Summary I had this unit replace 2 times (3 radio so far) at dealer. Every winter, this unit freeze and unit stop responding to Bluetooth and display stay black. Recharging front part and keeping it warm help but if my car can sustain Canadian winter, why should my radio can not do the same!?! I will have this radio replace by other brand. I need reliable Bluetooth.
Pros If you can find how to change the colors of your GPS navigation system... well, it's the cool thing on your GPS. That's it. No.. I forgot, it's good looking. But that's it! It's not a cool gps at all.
Cons I know I used to have a Garmin Zumo... which is great. But compare to that, the Avic-u310bt is total ****. I don't understand how can they provide such a gps and pretend it's a gps.
Summary Not intuitive, not easy to understand, no useful at all... and regarding Pioneer, well no service, no updates provided, a complete waist of time, and money.GPS: Strange POIs available... ?? Excellent hardware but really poor software in it!

Many minor fixes would benefits a lot to this radio/gps/cd player.
Pros Combines car stereo, mp3 playback, sat nav and bluetooth hands free all in one package
Cons See below for detail
Summary Bluetooth is bad and very difficult for the person you are calling to hear what you are saying. TMC (Traffic Message Channel) only works about 0.1% of the time so basically if there is traffic / roadworks / an accident on your route, you'll never know about it. Would have been good to have DVD / XVID playback but they obviously kept that back for their more expensive models.
