Hello! This is of interest to me as I am thinking of buying a 2018 Tipo estate. It's fairly cheap, and, I am a cheapskate!
Anyway, the car has the little screen and I would like to upgrade it to a bigger screen. Reading your tales on here, puts me off a bit. I did have success when I used "Incartec" stuff when fitting different DAB stereos to Saab 9-5's a while ago. Other firms advertised equivilants that didn't work. I am NOT a car wiring type of chap BTW!!
What might put me off if Tipo's are as awkward as 9-5's when it comes to ICE new stuff, I might wait for a cheap later Tipo to turn up for sale....
The 9-5 radio cost whatever they cost, then you have to add probably nearly as much again for fitting looms, SWC control boxes, aerials, fitting surround frames , interfaces, patch leads etc..
Enough of me wobbling on. Hope this might help someone!
