yeah I do, the DR400g-HD was my first ever dash cam, then a year later I bought the DR500GW-HD, that's why I have had the 400g for a few years and only used it for 12 months. both are utter garbage, just the 400 is much more garbage than the 500, probably as the 500 has the custom firmware on it making it better.Not sure why but I thought you had a newer model than this
didn't know that was possible, I must have a look and see.Check ebay, sort by closed/sold listings so you can average out the price.
