I bought it with GPS module and OBDII power cable.
Package arrived in good condition, not damaged. I installed it and tested for one day and can give some tips for the people who consider to buy this dashcam:
1. In user manual (can be downloaded from manuifacturer website) said that OBDII power cable can be used in vehicles built in 2003 or later. I used this cable to power IROAD X1 dashcam in my beloved Subaru Legacy (2000 MY) and can confirm that it works fine.
2. when I unpacked OBDII cable I was surprised that only two pins (+ and - from battery) were used in OBDII plug. So, I was sure that such features as parking mode, motion detection will not work. After testing I can confirm that, after car parked, leaved by driver and locked, dashcam continues to capture video for about 6 minutes and then goes to "standby" mode, starting to capture video only when motion detected. After driver return, when engine is started, dashcam goes to normal mode and starts capture video. Switch on OBDII plug must be in "P" position. (thanks a lot, Mark)
3. to view captured video on your PC, you need to download latest viewer from official website. Otherwise (if you installed viewer from sd card with your videos), Google maps may not work (my experience).
4. and, the main thing - your mobile phone MUST have English as interface language. Otherwise, your mobile phone will be disconnected from dashcam after 5-6 seconds after connection, needed to reconnect manually (no automatic reconnection). And it will repeats and repeates and you will be unable to properly locate your dashcam on windshield (no liveview) and to properly set some setpoints. In my case (my phone used Russian as default language), everything started to work fine ONLY after I switched language of my mobile phone to English.
