Everyone, happy new year in advance. My friend want to update the auto radio navigation for 2008 Audi A3, We find the Seicane S127683 which seems work well for it and we are looking for other brands such as pioneer etc. Do you know which one is better or any other brands you recommend? I really apprecaite for any input.
