This unit was quite easy to fit, just take your time. getting the trim panels off and back on is the worst bit (4 hours total). Didn't think it worked too well to start with but after fiddling with the settings, and I suspect, some learning by the car or the unit it now mostly works. Confusing with the Carplay and Jaguar XF (wifi) options in the Spotify app (on my phone, not the screen). When a message came in or the phone rang it seemed to default back to the Carply setting and I lost the music and Google Maps prompts and had to manually switch back to the Jaguar XF (wifi) setting through my phone (a pain if trying to drive - have to stop), but it seems to have learnt not to do this now. Don't claim to understand it but it now mostly works. When a message comes in I think its read out but the volume is too low to hear and I don't know how to change it. When I click on the message it asks me, first quietly, what I want to say in reply then, a few seconds later, asks me more loudly. Haven't solved this one yet. Mostly very happy.
