Hello, I own a Seat Ibiza Cupra Bocanegra (BJ 2010), I am very satisfied with everything, only the car radio (BILD1 in the appendix) is not quite up to date for the year 2015… That’s why I would like to have a new model with touchscreen, Bluetooth, etc. installed (BILD2 in the appendix). I would like to have the following questions: – If I buy a new original seat ibiza radio, does it fit perfectly into the current housing? And are the connection cables exactly the same? I realize that this is not an original radio… – Is the new radio also perfectly compatible in terms of functionality? Does everything work, not that some functions will not be available? For example, the USB reader is currently overloaded quickly on 8GB disks. Will this problem be solved with the installation of the new model? – How difficult is it to install the device? Do you have to install it easily and connect it or do more (e.g. programmie) – What costs do I have to reckon with if I just want to buy the device and mount it myself? And do I have to buy it at Seat or are there good online shops where you can order it? In case half of the questions would be quite “dumb”, I ask for patience because I really have very little idea of the topic
