Great and cheap car charger
So I got today the car charger I ordered from ebay for 3$, http://www.ebay.com/itm/400281723676...84.m1497.l2649
Its a 2.1A max output charger and the phone is gaining charge while being used with gps.
Edit: A little update:
Yesterday I had 2 drives with the phone the charger connected and the gps on, first was 50 minutes second was 35, both times everything worked great and the phone got charged.
Today as I was driving back home after the phone on with the gps and the charger for 10 minutes I received a "battery temperature too hot, stopping charging".
I can relate a few factors to this, first when i entered the car it was scolding hot, second probably the car mount was also hot and 3rd my case is really cheap and chocking.
I downloaded a battery temperature widget and I'll check the battery and the charger in a few different situations, with and without the case when the car is hot.
Edit: I checked the current the phone takes while being connected to the wall and the cat charger and they are both approx 860mA so the issue comes to the phone itself.
