Hello,
I will outline steps you can take to try and resolve this issue.
1)Update the MGPS with latest software. You can find software updates for Lowrance products on the following page.
Click here for software update pageAfter you update the software and you still can't acquire a sat signal, I would recommend a reset of the device. First a soft reset which will retain your GPS data and way points. If that does not work then a hard reset which will delete saved data and restore it to factory defaults.
Soft reset
-Turn unit off
-Press and hold the PAGES key
-Press and hold the PWR key
-Release both buttons when the USA map appears
Hard reset
-Turn unit off
-Press and hold the ZIN&ZOUT Keys at the same time
-Press and hold the PWR key
-Release both buttons when the USA map appears
If none of the above solutions work, you may want to reach out to Lowrance technical support. Below is a link to email support for Lowrance.
