Use the pump for my Golf 6. Dipstick out, pump hose in, pump, done. The pump cylinder sits a bit wobbly on the container, but you don't necessarily have the feeling that something is about to break off or break. I like the long, thin, stable suction hose. The pump stands on the floor in front of the car when it is suctioned. I am satisfied and have not regretted the purchase until now
The multiplexer meets the expectations fully and serves all functions, in particular also controlling an autopilot via WLAN. Over UDP several devices (iPad / iPod, PC, etc.) can connect at the same time to display NMEA data. With iNavX on the iPad, the autopilot can be controlled automatically via TCP. If you have any questions, a German-speaking support (in NL) is available competently and very quickly. The software has been and is constantly evolving.
