Because the device is good, when it comes to BT, Navi and sound. Everything is very good! Now little detail.
The installation took about 30 minutes, with connect and screw everything firmly.
It is urgent to read the manual before to later "complaints" not zuzuschulden the device sonderm the "installer"
It is certainly not to be compared graphically with a TomTom or Navigon have both been in use BUT, here it comes. It is perfectly adequate, very good even, and a neat navigation is possible if you connect everything as you would, "said" Pioneer gets. The Graphic is also adequate and well cleaned I think ... because I do not care where the farmer in which digging is traveling on his field, because this is on TomTom for example with it. The NavGate not 930bt. Thus, it looks kind of empty, but the Navi thinks. Show what roads you always left and right can be, also you can set the "height" of how much air the meter map is displayed. Just like POI's, this one can show or hide. You can also manually during navigation can be faded yet, Tanke, workshop, etc ... everything is possible and everything so far to date. What is also made very cool, if you stand at an intersection or have to turn left / right, It is again shown graphically as an image of a bird's eye view. So you have not at the chance to go wrong.
I have extreme respected it, the NaviPfeil has always been the same on the road, there was no Abwweichung mm. The voice comes quite promptly and quickly, very pleasantly surprised by the leadership.
The km / h were reported to me the same as the Navi on the iPhone. That shows me that the device is working properly.
I am very very happy and would have quite honestly, people also recommend the interest in a DoppelISO device.
Unfortunately, I can not understand all the negative statements that lags behind her or with the device 70 m can be expected? I have the problem that is not! I'm not going on the when I go on an AB box!
It is even in the manual there, if you one thing or another cable not anklemmt eg speed pulse), there may be delays or inaccuracies! So not mekkern but read!
The availability of the device is, however, given normally after 4-6 seconds, the sound you hear after 1-2 seconds, depending on whether the radio or CD, CD takes 1-2 seconds longer because reading speed. So ignition on, the unit "moves" up and you can operate after 5 seconds. Again, no big waiting times.
So also here TOP!
Throughout the unit of mine gets a "very good".
Has my expectation, despite all the negative criticism, most fulfilled until now! And recommend it to everyone!
Navigation works tadelos provided you include it on the way from Pioneer recommended)
Audio, powerful sound and clear
BT, everything went fine, you can use their iPhone in the audio mode also on radio via BT !!!
