I posted these questions elsewhere on Briskoda and got no nreponse so I'm trying again here.

Based on the 400HD v2 with 16Gb miniSD:

1. It says update your firmware but I cannot find it anywhere on the blackvue website, but I can find it for the 400v1 on the blackvuehd website (late edit: I was looking at .co.uk instead of .com) - any advice please? (another late edit: I've been going backwards and forwards while typing this and found this link www.blackvue.com/en/contents/sub3.asp?serboardsort=29 [sorry, I'm using a new laptop with Windows 7 combined with Firefox and it appears I have no longer the ability to add links, emoticons, etc while on the forum!] - is this the right firmware to install?)

2. On the blackvue website it indicates on the left side under "Who's Online" that there are so many visitors and so members online - is there a forum and/or how do you become a member? (yet another late edit: this was based on the .co.uk site)

3. When viewing the blackvue software to see the clips there is a G-sensor Pane (top right on mine) which has a blue line & yellow line & purple line and the letters TB FB LR - I get the gist of the sensor (ish), but there's no mention of the letters - LR = Left/Right? FB = Forward/Back? TB = Tuberculosis?

4. MyWay Viewer - it has a symbol for 'locate the vehicle' or 'find my car' - I click on it and is does nothing and I cannot find any further reference to it!

5. Knowing no different, I have opted for High Compression, HD & 30 frames - I welcome pros and cons of my option please.

Having the same camera installed maybe I can shed at least some light.

Q.1. I asked a similar question via http://www.blackvue.com and was told that there's no update for the v.2. Presumably the factory installed version is still current. Where do you get told an update is required?

The u/d you mention is for v.1 so I'd give it a miss.

Q.2. Not using the UK site I can't say.

Q.3. & 4. I'll have a look either later today or w/e, & possible come back.

Q.5. I use the same settings and things seem to work fine, so see no reason to change.

Q.3. Your right in what you say. If you go to Settings in the main view, then Sensitivity, Advanced and run a clip you'll see it in action.

Q.4. To be honest I can't see the need for this. It's all in the main screen Map view just not as big. If you double-click the Find My Car icon the map centres on your car, but as far as I can see that's it.

What version firmware is installed? (prog info, top right).

Hope some of this helps.
