You need to be careful doing this , ideally read the TSB and have an original if not first generation set of disks. Avoid the temptation to download bit torrent , otherwise you could end up with a wrecked unit that not even the dealer can fix. If you are intending to update the unit , you should also be aware you need a map DVD later than 05.2005. If you update and use the earlier map DVD from 10.2004 (originally installed) the PCM can overheat and become damaged. Get the updated map DVD , then PM me for details on the update. If you have a 2007 map DVD , it is possible you will also need a 2005 map as well. There have been cases where the the latest MAPS will not read after update , the update is done in two parts , the first part on the PCM and the second by the MAP DVD on the navigation unit. If you try to advance to the latest map DVD without previous updates from earlier maps there can be issues.
