All of us that have used GPS software in the past have experienced the misery of realizing that GMM will not allow any other large programs to successfully run while its 6+MB footprint is in memory. Well, I now have the latest GMM version and a 750 Treo with WM5. I have not tried any GPS software with this combination. Have any of you had great success with a hardware/software GPS combo in regards to the type of setup I mention above? If so please give me some details and any pros/cons that you can see. Thanks ahead of time.
