PCM File Format.. POI's for Speed cameras and such..

Recommended Posts

Just curious if anyone has found any documentation on what format the data files used for the PCM 2.1 are..

Reason I'm asking - I have POI databases that I subscribe to for speed cameras and red-light cameras, plus speed traps. These are quite useful on my Garmin GPS's (they beep and flash a warning for the POIs), and it would be nice to have this capability on the built in PCM. Right now I've had to end up using my Garmin on the dash when travelling places like Washington DC (probably the greediest local for speed cameras - apparently they're funding their entire city budget using them..) and this seems rather silly when I have a built in GPS.

So - anyone know the format used? There are lots of tools out there to convert from one format to another, and adding or modifying the POI data on a legitimately owned Navigation data disk does not violate copyright provisions as long as you paid for and are the owner of the original disk. (I know and totally agree with the provisions on this forum - and others - against illegal copies of intellectual property, but in this case - that isn't what's being asked.. this is to add info to a legally owned copy.)

I figure probably someone in Europe or the UK has already figured this out.. so any clues would be a wonderful thing. Or perhaps they've found a way to upload them to the GPS personal location entry database..

Have had a good hunt around this side of the pond (Uk) & can't find anything useful here either - even 'Pocket GPS World', who have all sorts of great stuff have come up with a blank. I presume if you could get hold of the latest Navteq map data, in their proprietary (.db from memory) file format, you should be able to 'compile' a new DVD, with the up to date files but the same basic DVD structure. I haven't been a proper geek for years now, but if I get a couple of hours spare over the next few weeks I might experiment - will post back if I come up with anything...

This post is 6+ years old, and you'll have much better options nowadays. Just use one of those popular apps like Waze, it'll be real time up-to date and takes minimal effort to download and use it. 


Actually, Garmin (and other after market GPS systems) have excellent update programs, and the POI Factory has proven hard to beat when it comes to extremely accurate red light and speed camera locations that are updated weekly.  We have several customers that run Garmin in  dash systems and use the POI Factory, and are very pleased with both systems.
