iam ready to upgrade my z1 with the 2010 maps and software, i all ready upgraded it to the z3 maps and software last year. my question is do i have to unlock my upgraded HD or do i just use acronis to upgrade the new 2010 software and maps, again my HD is upgraded and it has already been unlocked and has the 2009 maps and z3 upgrade software. can i just use acronis ??????????????

As long as you disabled security on the drive you can just use Acronis.

Thanks for the tip just one more questions do i have to format the drive or can i just upgrade it to the 2010 maps and z3 software. with out the need of formatting the 2009 maps and software off the HD?

No need to format. Acronis will give you the option of deleting all partitions.

Thanks guys your the best keep up the good work god bless
