MIO Speed Camera database

Well, yes and no, I guess.

Sallyann may know more about the specific workings of the Mio, but MaFt is king of the PGPSW speed camera database Exclamation

It's too much to expect everybody to know everything about everything and we wouldn't need this forum if we all knew it all - but the important thing is that people try to help others with what knowledge, thoughts, inspiration etc they may have.

I just spend too much time on it, when I should be doing other things.

Good point Sallyann

If this is a known problem amongst PGPSW members, I wonder if anybody has contacted Mio.

I might try contacting them myself on the assumption that a duplication is better than no communication.

If Mio correct this issue, it will surely benefit MaFt's hard work with the PGPSW database as well as the Mio speed camera database.

Hi all,

Having glanced through various postings found in this forum, I have come to realise that the *.mtc file format is used for speed cam data.

Perhaps someone can explain to me the difference between the *.mtc and associated *.upd file found on my PND, and the use of the SPUD format files.

When I first purchased my Mio, I was unable to successfully record new positions of cameras.....only once I created additional folders within the Miomap directory did the device create & store a SPUD file.

Thanks in advance
Midgley

North American Mio units don't seem to use the mtc file. Instead they have a subdirectory under MioMap called POI\SpeedCam. This subdirectory is initially empty on new units. When you create your own speedcams, a file called SpeedCamUpdates.spud is created.

I wrote a spreadsheet editor/importer for this spud format, so I had to figure out a few things about it. It stores one record per camera location, including cam type, angle and speed limit information. The file is a simple linear file which grows forever - records are never actually deleted, just marked unused when you edit a cam or delete it in MioMap. The file is freshly imported by MioMap each time the program runs. As far as I can tell, there is no other speedcam database. This is all undocumented by Mio.

Unfortunately all versions of MioMap have a serious bug in reading the SpeedCamUpdates.spud file - the cam type is always read as a standard speed cam, and all angles except 0 are changed. Therefore only "All Directions" will work, and all cameras show up as standard speed cams, regardless of how they are specified in the file.

As far as I can tell, my Canadian Mio C310SX with MioMap 3.2 does not recognize or read a SpeedCams.mtc file placed in the miotc\poi subdirectory.

If anyone has any ideas on how to find out whether is a way MioMap 3.2 can read a SpeedCams.mtc file with North American cam locations, please suggest!
