I just bought a Magellan 3120-mu, WinCE6, 64M, ARM1176JZF-S(Samsung Electronics S5P6443) 400mHz, 480x272, try to keep using Garmin mobilext and iGo primo with old Xtyler simple unlock as my launcher.
I prefer that simple Xtyler unlock as my luncher, as I used it at my old Insignia NS-NAV01, CE 5.00 (Build 1400) 64MB Centrality, ARM926T-AT4X0A (372Mhz - 400Mhz), 480x272 . I could run Garmin mobilext and iGo primo at Xtyler simple unlock + CE 5.0 +Insignia NS-NAV01.
Xtyler simple unlock launcher is running well at my new Magellan 3120-mu, WinCE6, 64M, 480x272. And Igo primo 2.0 at "SDMMC" and Magellan Navitagor at internal "HDD" memory are also running well, but ths Garmin won't start. It seems que.exe won't run. When I ran Garmin.MSCR or Garmin.exe in RunGMXT, the \Windows\explorer.exe flashed out and \SDMMC\Garmin\RunGMXT\TaskbarToggle.exe worked, it seems the GPS keeps RunWait \SDMMC\Garmin\Apps\WM\Que.exe with Taskbar shown. I tested all 3 Garmin.MSCR in the #1 post, none of them works.
