I don’t see problem. Did you enable the NMEA port? ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/c/c4036842cf399e9cd5b1841a6a7a7f2209b6756f.jpeg) ---

GPS Monitor is missing. I have the same settings as in your screenshot. NMEA works ok. ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/0/0d2538cada9d7318b1f35a4b2e05ebc870a0dd19.png) However I noticed one thing… Modem and Ports are visible only if I look at hidden devices. ---

It was in the beginning of this thread in Finnish. I stole this screenshot from @Donald and marked existing items by red ovals. Those buttons marked with yellow box are missing. ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/5/5a754218519d73664afdf85aec3f8c009e4ec003.png) ---

no idea why your skylight is not Sierra logo but Fujitsu logo have you uninstalled it and install again? > **[Skylight Windows Connection Manager for EM/MC series modules](https://source.sierrawireless.com/resources/airprime/software/airprime-em_mc-series-connection-manager/#sthash.FFQx82Kb.dpbs)** > > Skylight Windows Connection Manager for EM/MC series modules ---

I have installed and uninstalled this Build4814 Skylight.zip countless of times during last few days. This is Fujitsu laptop and there is carrier logo inside zip. And the zip is downloaded from the link You gave. There is a folder skins and there you can find Default\_66\*.xml for Fujitsu. There is also a logocarrier.png for Fujitsu. ---

Oh… Thanks for the hint 🙂 One new option “Connections…” and icon for it appeared after installing using the following command line: SkylightInstaller.exe /autolaunch=0 /advanced /defaultview=2 /autocreateprofile=0 /smsnotif=1 /smssupport=1 /alwaysshowconnmenu /alwaysshowbnonoffmenu /advfwimgswitch=1 /gpsmonitor=1 /gpsautosession=3 /desktopshortcut=0 ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/3/3182b5345781c680e7b61515b0d89fce6b404b38.png) I tried earlier Skylight.exe /h and Skylight.exe -h etc, but didn’t try it with installation package EDIT: Partial breakthrough… Run as Admin, but still GPS is missing ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/9/91698e4680faf8c3aa028dd44837e21280157331.png) ---

does it work for installation package? Here is my skylight registry, you can see if there is any clue: [skylight.reg.txt](https://forum.sierrawireless.com/uploads/short-url/zkRrMVb6EnvaZygSq7gGMgVYLnA.txt) (13.7 KB) ---

I have installed it as Admin. No big differences in registry. [skylight.reg2.txt](https://forum.sierrawireless.com/uploads/short-url/abjwxrXSW5NrAc9xttR1YTkZUHA.txt) (16.5 KB) How about GPS Monitor?

Thanks for Your efforts. I didn’t find solution to my problem. Finally I had to give up. It is not like me, but I must realize that it is more important to do some productive work than struggle with gps. When I need maps I have old Garmin mapsource & nroute applications and I’ll start using those. ---

Hi there. I know it has been a year since this post was formed but I for a long time struggled with the same situation with Skylight. I finally resolved it and I thought that maybe if you were still looking for a solution, maybe I could offer this. Within Windows Device Manager, there is a designated tab for “sensors”. Right clicking **sierra wireless location sensor** and manually uninstalling it AS WELL as the Sierra module in the “network adapters” tab, then reinstalling the latest driver was what did it for me. I was focusing on the module in the “network adapters” tab and neglected to explore more of the device manager to see if there were anymore correlating devices associated with the GPS functionality. Hope this helps you. Or anyone else for that matter.
