midnight Posted September 9, 2009 Report Share Posted September 9, 2009 I called Crutchfield and ask one of their techs is using the upgrade will write over any hacks you have on your system and he said "No, it will only update your maps and your 3d buildings but it will not overwrite any of your hacks. " I dont want to lose the self loading EZRIDER hack that I am using. Using the hacked upgrade or the bought upgrade firmware may be the difference. Can anyone that has upgraded their firmware confirm this? Thanks, Quote Link to post Share on other sites
adamdenterkin Posted September 9, 2009 Report Share Posted September 9, 2009 Alot of the hacks for version 2 and 3 are different. Another words It will not work BUT you can get the new hacked files instead of the old ones. Quote Link to post Share on other sites

No, you need a device key that's uniquely generated, it's one update, one unit Quote Link to post Share on other sites
