Hi Herbie,
I had Vline 2 installed about 2 months ago for about 2 weeks on my RX 450h 2018.
The reason why I ended up removing was an issue with the mouse/trackpad not being available on first start ( most start ups) until you switched screens via the Menu button and back again.
As far as I know, they were working on solution for it but I couldn’t wait until that became available and having to put up with the intermittent nature of will the trackpad work or not and especially if you already started driving and having to chase for the Menu button to do the switching.
The other reasons why I didn’t want to wait for the fixes was the way that the trackpad worked within the interface. In the Lexus ui, the trackpad can jump to the nearest button, making selections while driving easy. In the Vline ui, the trackpad is a mouse and as such, it’s not easy to control the UI while driving. Imagine having to use the keyboard on maps with a mouse while driving…
The positive of Vline is that they have a good customer service and I would give it a go again if those two issues are resolved.
hope this helps.
