I will be doing a few long distance trips soonish (2000 km each way) and thinking of using the phone for Navigation.The trip will be mostly sealed roads The weather will be warming up to the mid to high 30s and potentially higher. The phone is mounted to a Hondo Garage mount with quick charge and the buzz killer. So the phone should be able to handle the vibes. My question to experienced phone users out there is - Will heat be a real problem when using the phone for navigation. I have only used the phone in mild weather and have had n problems with the phone. I wont be storing the phone in a weatherproof case. So ventilation is available. Just that the phone is exposed to the weather. A plastic bag will be used in case it rains.
