I purchased a Z3 update hard drive from Garret last year for my Z2. When I saw he could update the maps if I sent him the unlocked disk back to him for only $40, I jumped at the offer.
I shipped my drive off to Garret on Wednesday (UPS). Garret received it Friday evening. He updated my drive and put it in the mail (USPS priority) on Saturday and I received it on Tuesday. Great service. Nice to have updated maps. All my personal data (music, phone book, etc) was untouched, so unlike the first time I got the Z3 update from Garret (new drive) I didn't have to reload everything. [i installed
