Cheers

That’s a car and a half. Love the Seats. Would like them in my Cupra but in Leather.

I didn’t know that the Cupra was available with Heated Windscreen. I’m guessing that it’s only available in Continental Europe.

In one box is HJS Downpipe(With Catalyst with ECE Certificate) in another box is JE Design exhaust This is all mods which are planned for now. Probably that after 6 years I will put it to Stage 3 so will get HPFP, intercooler, TTE 525R ...

Im find another solution to run JB4 Mobile app on car screen which work a lot of better than first one but need rooted phone. It also have better refresh rate, easyer to get JB4 app on screen after connecting phone, show dialogs(MirrorLink solution do not show them - so opening grapg or send log by email is not possible)...
HERE is quick video which show how work over Android Auto:
