I've been reading up on the bypass over the past couple of days and understand what to do but am having trouble getting the f500 to boot in WinCE. I put the test files on my SD card but the unit does not go into test mode, only normal use mode. I do have the unit hard wired with the Pioneer 4ch amp for the f500, so I am wondering if that makes a difference in the boot up. Any ideas?
