I have a z1 and just installed a upgraded hd. It is unlocked and I can add to the hd via my pc. When I install hd in my vehicle it does not recognize any albums. Is there a way to add music to the hd with out inserting 1 audio disc at a time. The last 1 took months of continous work.

Nope. No one ever figured out the encryption on the disc. Still have to do it one album at a time.

If you unlock your original drive, you can transfer the music parition from the old drive to the new drive.
