Greeting's - I've had a "Dash Cam" now for about 2 years. I have the Garmin Dash Cam 35. Pretty much bought one when they first hit the market. I did a lot of research before buying it. I have to say the Garmin has never let me down. Always on when driving, good quality picture during the day and night driving. If you bump the vehicle it will turn on an start recording. It comes with everything you need, but I did purchase an aftermarket mount, so I can turn and position the camera at a better angle. It also allows you to buy a faster and larger memory disc, to allow for longer recording times and more storage space. You can also take the camera out of the vehicle in case you need to snap a few pictures on an incident. I to live in Florida and the heat has never bothered the camera. I leave it in the car and attached to my windshield, with no issues. It does not record your audio while you talk in your car if your worried about privacy. Also if your driving and you see something that just happened, you can reach up and hit save and it will save the incident. It also alerts you to school zones, Red light traffic cams, and can also be set to let you know if your following someone to closely. Makes me feel a little safer knowing that its recording with all the crazy drivers out there. Hope this helps - Rich
