    Jirke, just to let you know, i have the GPS unit in the smart now, only have access in the car to the net until next week, but will be back into the site next week to sort the config for the tracking if that is cool with you.

    Also while i'm here, i have spoken to a few potential clients, and they all keep asking the same question. For busines use. Is ti possible to write an app that will allow 2 USB cameras (front/rear) to record through quicktime and be burnable to disc in the event of an accident....?

    The reason for this, is in the uk, the cost of insurance is greatly reduced to business if a recordable system is fitted to a business use vehicle.

    Cheers.

    The cameras are doable. However, there are (as usually) few issues:

    1. The current QuickTime API is a mess, while the Leopard API will be much better. So we are pretty reluctant to dive into the current stuff knowing it will be replaced by something better rather soon. Of course the delay of Leopard may make us to rethink this.

    2. If we implemented this functionality, it would have to be supported by appropriate hardware. The recording is useless if it is destroyed in the accident, isn't it? And that can happen relatively easily with a normal hard drive. So at the very least, we would have to have a sufficiently sized solid state and well-protected storage for the recording, perhaps even two independent storages at different places in the car...

    A quick question regarding navigation. I have a first working version of turn-by-turn navigation that reads kml files created using Google Earth.

    However, I am not really impressed by the quality of GE. The route itself is OK, but there are problems with address lookups and street names. It appears that although GE does know the names of the streets, uses them in instructions and can find businesses at these streets, it very often can NOT use them as either departure or destination points, which makes this rather problematic for navigation use.

    Is this just a local problem here and does GE work better elsewhere?

    Jirka,

    Here in the UK postcode lookup works well and one can easily use that for door to door navigation. Street number lookup is not as good but GE is, I would say, eminently usable.

    I like GE but the routing algorithms do not seem as efficient as the TomTom ones. TomTom to me is the gold standard for usability here.

    I tried the navigation yesterday on my trip from Prague to Holland and it did find the best route, same as TomTom. Routing in Czech republic was not as good, but still comparable to TomTom, with main problem being ignoring smaller roads. But I will play with it a bit more for shorter trips in the towns and see.

    Quick question, is the application Universal so I can check it out on my iMac G5 or do I have to wait till I get my new iMac? Pardon is this has been answered and I just missed it.

    You might want to talk to this group to see if some Mac drivers could be written. I think it would work great with the Mini.

    The app is universal binary. I develop on a MacBook Pro, my colleague OC uses a PowerMac G4. In the cars it is the other way around - I have a PPC Mini, while OC uses an Intel one.

    Giddy up! I've had my car-destined Mac Mini for a while, this is what I'm waiting on to install it!
