If you know what you want - a top unit

Vornweg said: Many features have not the power.
But the need is also not at all, if you know in advance what you want.
Personally, I had, as I have everything on the iPhone anyway, made to the objective, I can hear my music in the car without any problems from the iPhone and I must also use only a Navi.

First time ordering and delivery:
Tip Top. Ordered and the next day the postman will ring with the package.
So unpacked and inspected the whole thing.
The radio makes a very classy look and all "normal" cables are included.
In addition, I had a HDMI cable ordered, which I do not need, because with one was there to my surprise.
One uses like me an iPhone 5, but you still need a Lightning cable and an HDMI Adapter Apple Lightning (both together about 60 Euros.)
Installation I have myself done and was (apart from the vehicle-specific part) a breeze.
After I had everything reassembled first soundcheck. And here I can only say that the original radio is really a very good sound is recorded.

Functions out of the box: radio, speakerphone, showing the position (external GPS antenna included) Map. Not more.

Now the Iphone plugged in. It was immediately recognized and launched the Radio app, which you have to install before the AppStore. Now are the apps that are compatible disposal.
Where many believe that all iPhone apps run on the radio and can be operated.
Not even close! There are only a handful of apps, but which are more (who wants to find out in advance, which runs Radio app and looks)

There, despite offering little app, not even a star deduction, since I had a clear idea what the radio may need.
And these things it met perfectly! (I do not need a Facebook or Twitter or whatever the car radio)

Anyway, since the purchase of a Naviapp decency much choice now easier. (Here should be looked beforehand). Of the paid there are only 2 options in the end. Igo (who uses it already costs the extension for a further 30 euros per Radio App InApp purchase) or just NAVGATE which is IGO and has been modified right from Pioneer for 89 Euro.
When it was the 2nd variant.
The Navi runs fast and reliable, very fast route calculation and re-calculation.
Besides of course you can still listen to music and when the Navi has something to report, it will automatically be quieter.

Parrot handsfree and works perfectly. Even Siri works and writes as needed SMS etc. by pressing a button voice command.

Desweitern you can connect to the radio a reversing camera, which starts at engaging the reverse gear itself.

For me, this product, what I wanted and a strong buy recommendation if you have a clear idea what you want.
