I have 2015 insignia  i think it is 500 cd radio in i looking to upgrade it to 900 mavi but will i need extra stuff as i can disply on clocks on dash what in radio etc or could i simply plug in straight swap and would all menu for sat nav go on clocks or would need get installed

 

Pic of radio installed

maybe cheaper and easier to replace with an aftermarket unit that will still function the same but have more features and easier to update
