Update to my problem.
Sorry to say that my dealer cant exchange the rear lense. They offer me a 15,--€ refund which I accepted.
Hoping to find a rear lense which is not inverting. If someone needs an inverting lense and wants to get rid of his non inverting send me a PM

.
In the meantime I searched in e-Bay and found some lenses but they all used a power of 12V whereas the DVR only provides 5V.
Anyhow, as already known the rear lense picture is not very well, so I was thinking of mounting the DVR as rearcam and install a HD single cam at the dashboard as 2nd unit. The AV output of this device will be plugged in as "rear cam" into the DVR.
But currently I am not sure which cam I should use as front cam.
First the Blackvue DR400 seem to be a perfect choice, than I read about the poor reliabiltiy, in special the overheating and miss-focussing. So I was thinking about the DR500, then I learned that DR500 does not have an AV output any longer, only WiFi connection is possible

Finevu CR500 does not provide live streaming (referring to the manual), whats left...? Itronics ITB-100 (new version)? Price seems to be dropped to an acceptable level in the meantime (if its really the new version), but I didnt found a manual to look up some specs (i.e. if live streaming to an AV device is possible).
Any ideas or suggestions are welcome

Correction: the manual is a little bit unclear. Found first the chapter "Playing Videos" at page 19 which lets you think only previous recorded files can be played when attaching a monitor to AV out.
At page 9 and in some other posts here I now found that the Finevu CR500 is able to provide the live picture to a AV device

So may be this will be my new front cam...
