MY 2006 M35 mapping has been upgraded once to 7.1 I believe and I was wondering what results people have had upgrading to 7.4. Is this a software and mapping upgrade which makes the navigation system run better and thus worthwhile or could it be considered a slight mapping improvement only. If it is an overall system improvement I would purchase it, but if it would be hard to see any improvements I would probably pass. I have never had a factory navigation system in a car like this before and don't have any experience in system upgrades. Any input from people experienced in using these systems would be appreciated
