SDcard not recognized VDO Dayton pn6000

HI TO ALL..

I had installed miopocket 4.0 on my VDO Dayton PNA6000-WINCE 5 but
because of problems with Garmin XT I had to uninstall but the uninstall
did not do the best for me, now my SD slot dont read any sdcard i think
its corrupted registry and i dont have access to usb active sync only
have MTP (Media Transfer Protocol) when i connect to usb(no data
transfer). How can i access my resident flash(INTERNAL MEMORY) to edit
registry,change usb mode to activesync or something else???, i think sdmemory.dll is making
load problems.

Tnx in advance!
