I'm not sure I made myself clear - I installed the NAC in my car the other day and offered to take it back out and take some photos of the inside if you think it's relevant.
If your expertise suggests that there are no hardware differences compared to previous models, then there's no reason to disassemble the device, right?
Hallo!
Ich habe gerade einen Wave 4 HW21 installiert, aber nicht daran gedacht, Bilder von innen zu machen. Hat das schon mal jemand anderes gemacht? Sind Sie daran interessiert? Ich möchte mein Auto nicht umsonst wieder auseinander nehmen 
(Der vorherige Beitrag war meiner Meinung nach im falschen Bereich.
Entschuldigung)
Then I'm going to follow your advice and go for Wave4 non-HD.
Are the Wave4 HD and non-HD variants technically identical?
I can only find info about the HD variant.
They're still updating the RT6 maps, so I'm not worried about that, but more about the actual firmware of the device. That ends up being forgotten, most times.
7" non-HD, apparently
The seller told me that I can't install wave 4 in the DS5 because there is no 7" HD screen.
Hello,
I'm upgrading my DS5 from RT6 and would like to get one of the devices mentioned in the title.
As far as I'm aware by now, W3's downsides are the multiple incompatibilities with DS5 - lack of a decent Hybrid module, very poor camera image and other such inconveniences. On the plus side, being a newer machine, I'm guessing it's going to have a longer software life cycle and will get updates for longer.
19W2 seems to work just as fine, without the forementioned little annoyances.
Is there anything I'm missing? Should I go for the W3, change the reverse camera and live with the lack of DS5 features?
I must agree with Arminius, that has been my experience also.
Bear in mind that even the most expensive blades don't cost nearly as much as a new windshield, so don't go out and buy the cheap ones. They have a tendency of getting harder faster and end up scratching the windshield.
I've had a very good experience with PSA blades, for my DS5 they were ~60 euro. They're about 2 years old now and seem to have minimal wear - wiping is still as effective and they're completely quiet.
