http://www.amazon.com/review/R..._perm This guy has apparently had some major issues with it, especially his 1 - 4 points.
Alot of what the individual stated is true, but some of it was just bad luck, and I think... he stated he got his unit for $1079.. I know the site that he got it from because they were the only ones offering it for that price...that means he got some of the very first ones which may have been Beta versions being sold as New units, or he may have gotten ones that had fallen off a truck or something, because the whole freezing up issue and no displaying routes seems like internal damage, especially on a unit that doesn't have a harddrive!
Regarding the POI's, I mentioned in another post that the Garmin navigation systems have their positives and negatives when compared to Pioneer.
Accuracy: Garmin is like 5 x more accurate regarding its navigation software. Poor navigation has always plagued Pioneer. SOmetimes they give redundant routes, or have you turn right then make a U turn rather than just making a left turn. Things like that. Also, even with its new "Point Addressing", Pioneer Navigation is still very inaccurate, and only gives directions to a certain range, i.e. if you type 5705, it'll tell you you've reached your destination as early as the 5200 block. Garmin (Kenwood) navigation is accurate to within 2 meters. THis is very interesting because Pioneer uses oth an internal gyro sensor as well as tapping into the speed signal to guesstimate direction, speed, etc, and its still less accurate.
POI's: This is a no brainer... Pioneer wins hands down! Pioneer employs 12 million POI's as opposed to 6 million for Garmin, and almost every other navigation company. Also, you can search by phone number in Pionerr, where as you can not in Garmin. Oh, and the Avic Z3 has 3D POI's, which is another really cool feature.
Navigation user interface: Pioneer wins this also. Pioneer has a better GUI than Garmin, that's because Garmin was meant for everyday folks, where as Pioneer's navi is meant for more advanced users. Thus, there are many more ways toc change navigation routes, add way points, etc. However, this also tends to confuse most users, and many don't use 1/4 of the navigation options anyway!
So, regarding navigation, if you just want to get from point A to point B accurately, then kenwood (Garmin) wins, if you like fancy GUI's when you're searching for places, then its Pioneer, but ironically, you my get lost or sidetracked / rerouted getting there.
Oh yes, one other problem with Pioneer's inaccuracy is calculating current locations, sometimes, it thinks you're on a side road and you're on the expressway above the side road, then it'll start asking you to make a U turn when you're on the expressway... VERY ANNOYING!!!
AUDIO/ VIDEO
There is no comparison, Kenwood DNX-8120 blows the Avic Z3 out of the water in every way possible regarding the Audio/Video aspect of the unit. From its multiple USB inputs (only good for MP3 and WMA) to its super advanced sound processor, to its 5 volt preouts (vs 2.2 volts in the Pioneer), its ability to control external powered devices (LED's, neon lights, etc) and its BUILT IN BLUETOOTH, it is hands down a better A/V unit than the Z3. And for the guy on the review complaining about the bluetooth sound only coming out of one speaker, he just doen't know how to read directions and change it!
