I purchased a 60GB Z3 upgraded Hard Disc from Garet Toomey and it is working flawlessly on my Z2 unit. The maps are much more recent, the drive seems much faster than the original, and I now have 40GB of storage for my music. The Hard Disk was delivered to my door in Canada in 3 days of paying. The guy was great to deal with. The instructions are very easy to follow and I had my unit swapped out in 5 minutes. The little screwdrive that was shipped with the unit is nice, but I used a bigger handled phillips screwdriver for the 4 phillips screws. They are in there really tight and I found that the phillips srew driver supplied was not a perfect fit for the screw. The #8 Torque was a perfect fit for removing and reinstalling the cover plate.

Thanks Garet......YOU THE MAN!

I uprgraded my Z2 to a Z3 using Garrett drive service. Worked flawlessly. GC

I stopped by his home and had him do it for me. Looked super easy (i was just in the area) and works amazingly well. Now if i could just figure out how to load all these mp3s in a more efficient way.
