I’ve been quite satisfied with my Garmin Nuvi 1490t, except for the occasional spontaneous reboot. Recently however the reboot frequency increased dramatically, so I decided to contact Garmin through their website and ask for support. Below you’ll find the answer which really solved my problem. I haven’t had any reboot since I applied the solution.
1490T reboots every few minutes.
No pattern recognized. The device did reboot every few hours or
so when I just purchased it. During my most recent journey however the
frequency of reboots was on an average of 10 minutes or so. Varying from
1 minute to half an hour.

This video is fake fix all hes done is resolderd the legs that hold the usb plug to the board, its the 5 strips of solder in between the two legs at each end that are attached to the electronics, so the problem of rebooting has nothing to do with the legs on each corner, this guy is nothing more that a wanna be engineer, and is not true to himself or others. what a muppet
If this solution does not work you probably have a problem with the micro usb connector on the back of your device. If you are handy here is the link to fix it!
I’ve done everything as described but the problem stays as it was – every time my Garmin 1490 keeps rebooting with showing picture of device connected to the PC.
No it does not work if you have current firmware. My issues started with most recent update 2015.40 map and current firmware.
Brilliant! Worked perfectly and saved me from buying a new satnav – thanks!
