+ Good to very good sound
+ Reliable, no "hanger"
+ Useful to good reception (antenna adapter with phantom power)
+ Swipe gestures for title / folder / channel / tape control (slow up / down left / right Wipe)
+ Bluetooth telephony useful, menu selection numbers well (tested with Android phone)!
+ Bluetooth audio transmission and track selection +/- work on the car radio
Set -individuellen image background (jpg-Import) is faulty
-Bluetooth Audio transmission: song name, etc. is not transmitted on Radio (indictment)
-USB Stick: often "Can not read device", after few seconds will still always read
-USB Stick Audio Selection: a bit slow ...
-250GB HDD NTFS: is obviously not read (have broken off after a few minutes), is presumably. to NTFS, the radio can probably only FAT / FAT32 ...
-Video Files: Forward unusable slowly, jumping impossible (does not apply to DVD)
-no alignment of different volume levels when moving from one source to another (eg radio -> USB)
-Traffic-Program: at normal radio you can * this announcement * (ie temporary) off during a TP announcement with one tap TP. That does not go with the JVC so.
A / V and reversing camera not tested.
TIPS:
-----
Use swipe gestures, they are apparently not documented (see above).
If you want to save the Gefrickel with the handbrake signal can simply connect it to a screw on the radio (= ground) cable. Then your viewing goes on, but this is not permitted for good reason!
Connect the power supply for the antenna ("phantom power") to the dedicated cable of JVC! Otherwise the antenna sucks the battery empty.
Ignition positive place to permanent power or put ignition positive to terminal 15 (fuse box, for example, empty space in backup 25). In the latter case, however, the radio goes out then as soon as the ignition is off (and not only when the key is pulled, like the original radio, because that is controlled via CAN bus)!

UPDATE:

What I have noticed when making calls via Bluetooth: the selection of the party to be called is quite well resolved. Too bad that the phone number for incoming calls only, but not the corresponding name will be displayed, even though he is present in the device.
