Lucky you. I'm about to put a sledge hammer through my dash. The pos works as it should on BtSsm for a couple of drives, then gives the "USB device not available", so I reboot the Nexus and it comes back on and works another couple of drives. Then the other day I got in the car and started and the Nexus wouldn't start at all, dead as a door nail. So I took it out and back on the bench at work and the stupid thing has changed itself out of FI ( fixed installation ) mode so it didn't sleep last time I turned the car off so has been going the whole time and flattened the battery It's done that a couple of times on the bench at work too, and I've yet to figure out why.
Everytime I have to reboot it to get BtSsm working again the gauges go all to hell and I have to resize and reposition them
Also with Google Maps, I have downloaded some so I can use them offline. I have location turned on on the Nexus ( the little icon is at the top right of the screen ), yet it doesn't know where I am more often than not when I open the Google maps app. Then after I've been driving a while and I keep pressing the symbol which is the crosshairs inside the circle, sometimes it will finally work and know where I am, and then I can put in an address of where I'm going and it'll work fine. But more often than not it can't get my location for whatever reason. I'm always outside, not inside a parking building or under a concrete bridge or anything stupid.
Getting tired of having it in the car for 2 days before it shits itself then having it out for a week trying to get it to work and repeating the cycle. Starting to loose hope. Everything seems to be set so it should work properly, and it does every once in a blue moon, but it never lasts. Can;t for the life of me work out how or why it changes it's settings by itself for no apparent reason. I build race cars not computers, but it can't be that hard can it? I've got it this far??
