Garmin recommends not operating the device outside of the following temperature range: from -4°F to 131°F (from -20°C to 55°C). There is no external antenna available for this model.
Sorry, there was a problem. Please try again later.I am not sure about the operating temperature, but mine has been in my car all summer, and some of the days have been over 100, with no issues. There is no connection for external antenna, I seriously doubt there is a needs, I have never had an issue with it picking up signal. But you may have a unique situation.
