Navigation/Radio doesn't turn on after the battery issue

[ig77]

I jumpstarted the battery after it was low and was able to get the car to start. But, the Navigation system/Display/Radio doesn't turn on.

It was working fine for a short while until I stopped and started the car. Now it doesn't work anymore.

Could this be that the battery needs a recharge or do I need to restart the nav system. Thoughts on what and how to do?

Could be power saving mode. Get the battery properly charged first then see if it works. If not, could be the jumpstart was improperly done and cause some damage due to power spike.

I got the battery recharged, but it's not turning on.

I feel that this may have shut down itself and needs a reboot? Any thoughts?
