Hey, I hoped into my vehicle this morning to turn on my ipod and now it wont boot up.

When I hold the power button it will start to load like it wants to boot up but will never boot all the way, instead it will just turn back off completely.

I was just wondering if anyone knows how I could fix this or if it was even possible at all to fix.
And I was also wondering if the problem could have been cuz I left it outside in my pickup hooked up to my dock station, which is always charging, and it got about 25 degrees last night.

Thanks
