Garmin gps map 740s. Is only about 2 years old .Have tried master reset ,downloaded software update onto SD card and installed it . Still not receiving any satellite signal
Electronics Technician: Richard, Customer Service replied 1 month ago

This is usually an issue with the Firmware, so I would first like you to do this please.

Remove the charger from the unit and hold the power button to off for 60 seconds.

Release, then connect the charger and try to turn on the unit and use it.

Let me know the results please

Thank you

Firstly this unit does not have a charger .It is hard wired ,I tried turning the power off and holding power button down but that achieves nothing ,I tried same with power going to unit and same result .Looking at the systems details it says that it is running on software version 4.30 , also it says GPS SW 0.0 .I am sure it has something to do with the GPS SW 0.0 that is the problem ,looking at forums on the subject I am not the first to have this problem
Electronics Technician: Richard, Customer Service replied 28 days ago

Hi there

The charger is what supplies the power to it, you will have this connected else it would not be able to turn on.

Where exactly are you using the unit?

It is a marine gps so it is in my boat .I don't believe there is a charger connected to this unit at all .It is connected directly to my boats power system .If the power to the unit is turned off it will not do anything .Do you think I should buy an external antenna ,as the internal one doesn't seem to be doing its job ?
Electronics Technician: Richard, Customer Service replied 27 days ago

This can be the case, but first I want to ensure you removed the power to the unit for 60 seconds for a reboot.

Did you do this?
