I do not understand your question. What is the part2? There are 3 parts. The suction cup has a ball at the top with which it is pressed into the holder, part 2. You attach this holder to the navigation device, part 3. You can simply pull the ball of the suction cup out again, but it takes a little force.

According to my information, the car power supply supports 12-24V.

Yes, that's no problem. You can buy maps for the whole world from Garmin, or download free OSM maps to the device or micro SD. You can then activate/deactivate the installed maps individually in the device settings.

They say that they are all pre-installed. In any case, I have already needed D and F.

The 3 variants are described here: http://www.garmin.com/de-CH/traffic (under the title "How do I get traffic data on my device"). In simple terms, all traffic messages, but which are communicated via different channels, are These are communicated via different channels: Live traffic via the internet connection from the mobile phone, TMC via FM and traffic information via DAB radio.

I never had a problem with the Wi-Fi. At home, the navigation device is about 12m away from the Wi-Fi router - no problem at all.

In my case, the device must be connected to the power supply. Wi-Fi is set correctly?

Unfortunately, I can't say anything about it because I don't have a reversing camera.

I have the same one and so far I haven't had any wifi problems. I'm doing the login and password search and all is well.

that is, after 50 minutes.

Yes, of course! Works very well for me. But it takes maybe 3 seconds until the picture appears!

The suction cup has a diameter of 55mm.

Search for Garmin adapter plate or retaining clip (e.g. item number 2247226) - unfortunately I haven't found anything at Digitec!

This works via DAB (radio) and this is possible in many countries. The navigation system must be connected to the cigarette lighter with the original cable (acts as an antenna). However, I have noticed that the information is often not correct or accurate and I usually leave it switched off.

No, I've never had to do that, except for specific country changes....

Sì.

The unit can be charged with the enclosed USB cable. The message on the screen is wrong. From the old Garmin device I have a charging cable with transformer for the socket.

I can't help you there, but I connect my phone to the sat nav via the Garmin smartphone link app and then get traffic messages (and everything else) played on the sat nav. The reliability of the messages is more or less good
