We've had some pretty hot days in my area (80 degrees, plus) considering we just hit June. I have my car dock attached to the windshield with the suction cup. I notice after driving around for maybe 30 minutes or more, the phone is EXTREMELY hot. Usually, I have music streaming to the HTC Bluetooth StereoClip and I have Google Navigation running, which means 3G data is also downloading maps. And of course, in docked mode, the screen is always on. Is all this processor/radio/screen activity combined with the heat and direct sunlight too much for the phone?? Or should I just trust the phone can tolerate it and HTC/Sprint would never have released a car dock if it couldn't?
