You probably will not have any issue connecting to the GPS. However, in April 2019, the week number rolled over so if your firmware is not modified and aware of the issue, it will think it is starting time from week zero again, and the LS will interpret it as a date in 1980-- kind of like the Y2K issue new years day in 2000...
There might be a way to change the date manually according to this forum entry:
I found out from a couple LS users that their older mounts were having trouble with GPS, which I inquired about. They also did not find a way to enter date/time/location manually. I was told the LS fix was not complete yet, should be forthcoming. The reply for entering data manually is as follows:
The customer can enter the date/time/location manually by pressing the MODE key when the telescope starts looking for GPS. This will happen shortly after the telescope boots up and before any night sky alignment takes place. They can also turn off the search for GPS in the SETUP/PREFERENCES menu.
This hassle with overriding the date could take the joy away from using the LightSwitch. I remember at a star party, I turned the LS on and walked to the porta-potty. When I walked back to my camp site, the LS was all aligned! I did not touch a thing.
I remember when I had issues after April 2019, I was not able to change the date and time manually. The date and time was definitely screwed up. Updating to 1.6e got it working.
As I mentioned, after I had my LS for a few years, it seemed to need a firmware upload if I did not use it a few times a year. Reloading the firmware takes about 45 minutes and is pretty painless. Put the mini SD card in the unit, turn it on, and confirm the upload, and wait.
Unless you can override the date and time from the GPS, I don't think the GOTO will work. Pre-pandemic, Meade would sell you a preconfigured SD card if you can contact the support line. I would highly recommend that. Support gave me a link for the 1.6e firmware download and instructions to make the SD card. It was not straight forward and took a lot of messing around but I finally got a working SD card. Buying the SD card from Meade is worth not going through the hassle.
Anyway, Good Luck, and hope you get it sorted out-
