Having enough space to store all of your precious personal information is so important, Michdough. The Z Force user manual does recommend using a Class 10 memory card, and it looks like from the information you've provided, your card is a Class 3/Class 30. It does not specifically say other classes are not compatible, but Class 10 is what they recommend. For more information about this compatibility, you can reach out to Motorola at 800-734-5870.
