The installation takes time. This should be taken into account. I had decided on a reversing camera with flash-over meeting, because I wanted to draw any stripping. For T4 there are a reversing camera which will be exchanged with the existing license plate light.
The camera is connected via a dedicated contact in the lamp socket of the reversing light. But for the cable from the reversing lights must somehow in the tailgate. Müsam but doable. Tip: t4-wiki.de
Thus, the radio, the camera signal also indicates the power distribution box with a plug appropriate reversing signal is present. For the connections you need some cable and a few plugs; I had 1.5mm². Thus, the radio will automatically switch when reverse gear is engaged on the camera. Prima!
Unfortunately the reception was initially very poor because the T4 an antenna amplifier is installed, the on the radio gets its energy (phantom power) - For this there are special adapters that are connected to the ISO connectors. Then it will come off in the quality that you are used to from Gama.
During installation make sure that the 12V are plus not confused (VW has their own standard). The Tecker signal, all could fit - but this is not so. You will notice this at the latest because the radio no longer recalls the settings. But this is well described.
Up to this point everything is worth 5 stars. Why complain some reviewers about the "missing" CD / DVD, I can not understand: It's obvious that it there are other models. So swap and silent!
Cons: Despite the large display the mp3s in the selection are displayed garbled, titles can not only read - because each iPod mini can more :-(
The service is a bit messed up and tend not to use the manual. But I can hear radio and play my mp3s. Videos I testweise not get from a USB stick to play as MP2 / MP4 - not stöhrt me more because I look at any videos in the car.
Up to this point it is still 4 star.
But what disappointed me is the minimalist BT - As you would expect as a user something more and something is also possible with other suppliers: I want is running Radio / MP3, etc. but the messages of your smartphone BT heard by the current signal turned down and the announcements coming. Here's all MP3s wirelessly. But I still prefer from a star. Because that is not what I like then.
3 stars overall, conditional purchase recommendation
