The Garmin 57 is great little cam. I love the size – it’s actually smaller than the EZ Pass (brand name for the transponder for toll roads on most of the East Coast) mounted to my front windshield. The picture isn’t bad - it’s clear enough to read overhead road signs when fairly close to them & license plates (from about half a car length). The night vision is “ok” – it get’s the job done. Road signs (being very reflective) are quite visible at night, but I’m not really reading license plates at night (I believe my headlights are washing them out.) There is a setting for “exposure” which I keep at the default setting – perhaps I could improve the visibility of license plates at night by adjusting the exposure. But for the “bigger picture” (who pulled out in front of who, who sideswiped who, or who ran the redlight), they’re very effective.I am using a 256 GB micro SanDisc Extreme. I get tons of hours of driving time - not sure exactly how many hours – Garmin says 256GB will store approximately 18 hours (see Garmin’s chart in my attached pics). That’s a lot of driving time. I am using the parking mode & powering the camera through my vehicles OBDC port using an adapter (acquired from Amazon), that allows me to select 5 minutes of parking time or until my vehicle battery reaches 11.6V.The setup for the camera has quite a variety of options that allow you to tailor the operation of the Garmin 57 to meet your needs. If there’s something you want the camera to do, look carefully through the set-up options – it’s probably there. I am using the driving alerts which I kind of like. They include lane departure, following to closely, telling you when the traffic in front of you is moving at a stop light, etc. They’re not bad since I’m driving a Jeep Wrangler which notoriously have very little to no similar technology.The Garmin App (in my humble opinion) is absolutely worthless – I don’t think it’s possible for ANYTHING to work SLOWER than the Garmin App. I tried using it on Day 1, gave up & never looked at it again. Anytime I want to view a file I do it on my PC. I just pop out the Micro SD, put it in the adapter that comes with the Micro SD & pop it into my PC. The .MP4 files are located in the DCIM Folder & if you specifically asked the Garmin 57 to “Save” the file, you will find them in the “Saved” folder or otherwise in the “Unsaved” folder which will be overwritten when the Micro SD is full. I usually just go to the ”Unsaved” folder & view everything from there using Windows File Explorer. If there’s anything I really want to keep I simply copy it to my PC. The .GLV files are basically worthless to me at that point – they are just a very low resolution videos - I think intended to work faster with the Garmin APP – so I just delete then by doing a sort, selecting them as a group & hitting “delete”. It frees up a tiny bit of space on the Micro SD, but also gets rid of HUNDREDS of files that you don’t need. When you select a group of .MP4 files, go to the top one, right click & hit “Open”, your selected viewer will automatically play one after another in a “continuous” fashion. So you could highlight a whole group from a recent trip & watch the trip without touching your keyboard.So, in my “title” to this review I pose the question, is this device overpriced. I definitely think it is. I purchased the Garmin 57 over the more expensive models (67W) which provide a 180 degree view, not because it is less expensive, but because the 180 degree view was too distorted for me. I watched a super video on YT where the reviewer was showing the videos from each of the cams side-by-side, & very quickly took the 67W out of my shopping cart & replaced it with the 57 model. But here’s the reason I think these cams are overpriced. My home surveillance cameras (Wyze V1 - $25 & Wyze V2 - $35) (I have seven of them) have a MUCH better image than the Garmin 57. They have much better detection capabilities, and VERY FAST continuous playback through the app. These are $25 & $35 cameras & I think for the main purpose of a video camera (recording video), these cameras blow away the Garmin 57. Now you could say that I’m comparing apples & oranges but there are actually people who use the Wyze cams in their vehicles & when it comes to video recording – they get awesome results for a tiny fraction of the price. If they can produce a surveillance camera for such a low price that provides a better picture, these Garmin devices are way overpriced !!!
