Simple PSP GPS SETUP This application will determine the location using this simple PSP GPS setup. Deniska modified the connector on a $100 Holux GPS unit so that it could be read through the PSP remote port. A test program that works in kernel mode is provided. Deniska notes that this will probably work with older (read: cheaper) Holux units as well.
