Nexus 7 : Problem Keeping Charged on Long Trips Using Navigation.
I have been testing my Nexus 7 as a head unit and have not been able to keep it charged using turn by turn navi. Has anyone mastered this yet? It looks to me it's eating way more power than I could ever feed it. I have heard killing all the extra stuff running, turning down the screen helps. But what good will it do if it's maxed out running the navi.
I was planning this system on a new build but it looks to me it's back to the trusted old school, never had any problems like this the old way.
Feedback helpfull on this before I scrap the tablet idea
