Now I really like the sound of that... a hidden "black box" that uses data from the RNS-E to lookup a database and then drive the DIS - that would look "OE".
I think that's a project someone should be working on...
Custom POI's
Is there anyway to add custom points of interest to a backup DVD disk. I'm thinking along the lines of the UK speed camera database which is a POI file for PDA's and other nav units. Would be useful to get audio alerts when approaching these license endorser units at high speed. :roll:

With regard to faking TMC messages, this pdf file makes interesting reading.....

I like the sound of that! Where do I donate for research?Also there is a "thirth" way that works ok but needs some extra hardware, we can get the GPS position asking RNS-E (through CAN or K-Line) with a simple PIC, compare it with a database stored in a flash and send a command to the cluster for beep and warn in the dish, when I was working in a CarPC project for my A4 I tested it and works fine, but this needs a small pcb (similar to CanGate).
I was working on that two years ago and it works ok, but I didn't have any interest in that feature.Now I really like the sound of that... a hidden "black box" that uses data from the RNS-E to lookup a database and then drive the DIS - that would look "OE".

My goal was to use the DIS in graphical mode to show some engine values (turbo bar, oil temp, etc) but it was impossible, the DIS works in a very very hard (and strange) way so I quit that project, you can view some CAN info, circuits and discussions about thath here http://www.audisport-iberica.com/foro/index.php?showtopic=80345 (it's in spanish).
If anybody is working on that and want some info, I think that still have some rests of that in mi HD, but its very simple, small board with a PIC connected to K-Line, read the RNS-E channel which stores the GPS position, compare if with a lists of POIs stored in a Flash and if match, send a warn to the cluster, and optionally you can show a text in the DIS with the text SPEED CAMERA (then you need to implement a CAN adapter to the board, or use a PIC with CAN).

Can you explain to me how a Pogo Alert (or mobile phone software for that matter) would be useful camera alerts? - Say you are in an urban area, you come to a roundabout that has 7 exits, 4 of them have speed cameras - it will give you 4 alerts? - What if you don't take the exit that has a speed camera, how would it know?Hmmm, I don't agree.
I have a smartphone with GPS but I don't use it for this purpose - I have a separate detector (a Pogo Alert).
Why?
1) I would have to have a mount for the phone on the dash, which I don't want. I have the Audi Bluetooth kit so my phone stays in my pocket, where it's not visible to thieves.
2) it takes so long for it to get a GPS fix - several minutes at times (much slower than either the RNS-E or my Pogo Alert) - that I would be "at riak" when in a strange area.
Ok, say you are not in an urban area, but on a motorway and an exit you are not taking has a speed camera, it will warn you of that speed camera?
Wouldn't you have to program both the RNS-E and the Pogo Alert with your destination for this alerting to be of any use?
Pogo Alert isn't a sat nav ... so there's no programming of destination.
Let's think about how GPS based camera alert devices work...
Because they don't know your destination (and hence which roads you are likely to be driving on) they have to make assumptions. The main assumption they make is that you will continue in the direction you are currently heading.
In your first example you will get warned about 1 of the 4 cameras IF it's straight over the roundabout, and you won't get warned about the other 3 cameras unless you turn onto one of those roads and then only when the device realises what your new heading is. In theory a camera very close to a roundabout could catch you unawares... which is why these devices are NOT infallible and why you still need to be watching and looking.
And in your second example, yes you will get warned about the camera on the exit you don't take. This happens to me every day - I approach a roundabout intending to turn left, but I get warned about the camera that is 200 yards further along the exit that is straight on. That's a false positive I can live with.
All the above is why adding camera alerts to the RNS-E is a great idea, provided you have an active route it knows which road you will probably be driving on and can warn you about cameras on turns and not warn you about cameras on exits which you probably won't be taking.
This is the current "plus point" of a mobile phone with GPS and running something like TomTom Navigator - it has route information AND camera location information (because applications like TomTom Navigator support the special POI type for cameras, and free databases are available to download).

Check Out NavPOInt if you have an RNS-E, it'll allow you to install as many POI as you like. Unfortunately I've got MMI 2g, so am stuck.
The big downside of NavPOInt, as they admit themselves on their website, is that because of the limitations of the RNS-E software it CANNOT provide warning messages as you approach a speed camera (that you have added).Check Out NavPOInt if you have an RNS-E, it'll allow you to install as many POI as you like.
IMHO that means that the best solution is still a separate GPS speed camera warning device - because you can continue to use a genuine RNS-E map DVD (which is much better for longer laser life) and you then get warning of the camera (and the better ones also calculate and display your average speed through a SPECS zone).
