Found a review on Amazon
Hello...
Unit Cowon AW1...
First review on this product. While I had high hopes for it, I will say that it falls short of expectations.
1) The unit ger VERY HOT and shuts itself down based on the heat. Hello...this is made to be in the windshield of a car. It will be in direct sunlight. You need better heat sinks.
2) It DOES NOT HAVE a GPS Receiver. It is OPTIONAL however it is not available anywhere for purchase. In other words....NO GPS. For the price of the unit...it should have it already.
3) Hardwire install kit is also nowhere to be found.
4) Customer support from the company is more or less NON-EXISTENT. They do not respond at all after several emails directly, though their site, and via they Q&A system that you must register to use. NO REPLIES at all.
For such a company with a very nice looking site...it is hard to believe that this unit falls so short.
The video quality of the camera is nice, when it runs and is not shut down based on heat. It has issues detecting driving mode vs parked mode. (Ver 1.9 of firmware which is current.)
The app is nice, however while I can stream live video for setup... I can not stream videos that were recorded. It fails. To see the videos you then need to download them and then play them back.
All in all, lack of support. Lack of being able to even buy the "options", and it not being able to stay running based on the temperature (It was only 76 degrees out) makes this unit on it's way back to Amazon.
Such a shame really.
UPDATE - JULY 5th...
After taking a trip with it and needing to look back at some video. We were shocked to find how much was MISSING! Yes, missing. We would find gaps of 5 to 10 mins of time. It was set to record 1 min video files which should pick up right where it left off file after file. Nope, we would look at a file, then want to continue fron where that file ended so we would then play the next file. However, we came to find out the next file was 5 minutes later. (Heat issues again?)
Still, TO THIS DAY, I have had no contact from the manufacturer after 3 attempts. One even though their support website! STAY AWAY IF YOU THINK YOU WILL NEED SUPPORT.
