where can I buy a GPS software upgrade for my 2003 BMW 530i?

This is a factory installed system on DVD.

1. Ask a pro
2. contact a BMW dealer and they can sell the upgrade to you. also try ebay.com
3. www.navtech.com is where I got mine. Look to drop about $350 though for the set.
4. If what you mean by software upgrade is updated mapping, you can buy a new DVD at the BMW Dealer.
