q:have read your item description on the xc90 head unit and am very keen to purchase a replacement unit for my Volvo (dealer quoted $1200 to replace)
Because I am in Australia I would like to make sure I have every chance of getting the correct unit first time and not needing to send any back to you.
What information do you need to increase the chance of success? I am happy to remove the unit and check part numbers etc to get it right.

Any help on this would be greatly appreciated.

A: hi all I need is to know which one you have by removing plastic triangle from the door and sticker on the tweeter will be blue or yellow, also I need to know if you have a car phone once I know these I will send you correct link to the icm you need
