@YoDude:
_Encrypted_ OV2 files? I haven't heard of those before. I made tools to read and write OV2 files some two or three years back. Do you have an example of one of these new files? Or how to get one?
Thanks in advance

Sure

The attached zip includes a "Retail Stores" OV2 POI file from TomTom that can not be edited with conventional tools (Navicore Extension Editor and all other DB editors I have report "can not detect file type".) AND, a "Home Depot" OV2 POI file I built from the ground up that Navicore Extension Editor reads just dandy.
It is pro'ly a single line that throws the editors off but I haven't had time to find it...

Any help would surely be 'preciated.

EDIT: the file exceeds this sites upload limit so I posted it on a blog >> http://my.opera.com/yodude/blog/for-ta-t3-posted-on-itt

The Retail Stores file starts out right away with something that isn't normal OV2 at all.. the first byte is supposed to be 00, 01 or 02 (depending on the subtype of OV2), this one begins with 0x64. Your Home Depot file is a type 0x01 file and reads fine with my tools. Presumably the Retail Stores file also contain shop names or some such, but there's no plain text in the file so it's either encrypted or just compressed.

I'll take a look at this (probably over Christmas, as I'm going on mission next week and will only be sporadically active). I figured out the original OV2 formats from scratch (before I later found partial docu at the TT web site, lol), so maybe this one'll work out too.

EDIT: Here's some partial output that my old tools dump out. There seems to be some legit-looking locations there.. (the first 'Ignoring record type 100' is the 0x64 I mentioned above).

Code:

Ignoring record type 100;42896.95736,  64.85676, 42790.27950,  19.64521
;42862.39810,  64.85676, 42790.27950,  19.64521
;42862.39810,  36.57136, 42790.27950,  19.64521
;42851.20389,  36.57136, 42790.27950,  19.64521
;42851.20389,  33.83485, 42790.27950,  19.64521
;42835.06816,  33.83485, 42790.27950,  19.64521
;42835.06816,  33.20660, 42790.27950,  19.64521
;42832.52526,  33.20660, 42790.27950,  19.64521
;42832.52526,  32.75769, 42790.27950,  19.64521
;42791.83144,  32.75769, 42790.27950,  19.64521
;42791.83144,  21.34309, 42790.27950,  19.64521
Ignoring record type 28;42791.83144,  32.75769, 42790.27950,  21.34309
Ignoring record type 28;42832.52526,  32.75769, 42791.83144,  19.64521
;42832.52526,  21.28228, 42791.83144,  19.64521
...

Compare this to your Home Depot file:

Code:

;42881.27549,  64.85918, 42790.28814,  19.68855
;42862.54722,  64.85918, 42790.28814,  19.68855
;42847.73596,  64.85918, 42790.28814,  19.68855
;42831.72602,  64.85918, 42790.28814,  19.68855
;42831.72602,  37.95230, 42790.28814,  19.68855
;42830.00244,  37.95230, 42790.28814,  19.68855
;42827.76049,  37.95230, 42790.28814,  19.68855
;42827.45250,  37.95230, 42790.28814,  19.68855
 42790.28814,  21.97187, "Lihue - Kauai"
 42791.62059,  21.33261, "Kapolei"
..

(My tool prints Type 1 records with the ';' in front, Type 2 records are those two last ones with names.)
Looks promising. We can get back to this later (presumably in another thread, not hijacking this one..) over Christmas or thereabouts.

Thanks dude... and have a happy holidays!

BTW, both files load and run in TomTom fine... TomTom apparently just started doing this with the POI's that they provide free or otherwise.

What am I doing wrong? When I try to download POI, I get "File not found". I just installed Maemo Mapper 2.2 last night. If I go to the Source URL in my desktop browser, it's indeed not there. What is the correct POI URL? I have by default, http://www.gnuite.com/cgi-bin/poi.cgi?<arguments>

This is on a 770 with OS2006.

thanks,
Frank

There's also a DBUS interface for Maemo Mapper, which doesn't have a "send address" function yet, but will soon.

But how to send the address information from the browser to Maemo Mapper is the real problem. djs_tx's suggestion (a network daemon listening for certain network traffic patterns) may sound straightforward, but the kinds of patterns to look for are likely complex and non-constant. Roger's idea is likely impossible without access to the browser's source code.

I am having the same problems on N800 running OS2008 (even when it was still OS2007)... I've been asking around on other threads but no answers so far... I guess we just have to wait, maybe it's been worked on.

Does anyone know now I can use my TomTom V5 on the N810 or N82...(santa said I have been good this year...<g>...)...

I have tomtom on my Treo 650 and the Nokia GPS maps on the N82 is not worth the $150 3 yr lic, IMHO...mostly due to the typing...yet the google mapping is very good...I currently use the N770 and would like to move the TomTom over to either the N810 (soon to be here..Dell states by 1/6/08) or the N82 as I find the tomtom mapping outstanding to use...

Regards,

David
