Been a loyal OCN user from the beginning.
Upgraded to OCN5.
Followed their install suggestions, i.e. install to BIS.
I think they also say install to main memory? (in some places). The program needs that to be able to run though...so that doesn't make sense.
The missus was having problems with her PDA.
Asked me to do a re-install of the apps, make it all tidy etc.
Looked around on here and found some discussion on SD/CF/BIS (decreasing order of memory speed).
Thought I would try installing to the CF card instead.
It's a high speed card, after all.
The difference is *Night* and *Day* in terms of loading and performance.
I have no idea why they recommend installing to the slowest memory.
It really cramps the style of the app.
I have emailed them to let them know my experience.
Thought I would post here as I am probably not the only one who needs this info.
Hopefully this has not already been covered (I couldn't find it).
We both have Dell Axim X50v. Which I also upgraded the ROM on (A01>A03>A05).
Love 'em.
Cheers!
p.s. If I have just been an idiot and not understood, that's fair enough. However, they do say specifically "we do not recommend installing to CF/SD" and this clearly is the place to install to, from our experience.
I too have OCN installed to CF without a problem but was never aware of their suggested install location. It's been my experience that most navigational software works from memory card; after all, the maps would fill up the internal memory in no time!
Installed mine to just a regular speed SD card, and it works like a champ.
One piece of advice ---- after exiting OCN5, do not immediately turn off your pda. OCN writes to the defaults.ini file (or maybe it's the prefs.ini), and if you turn off the pda to quick, you will corrupt this file! The s/w will then not work.
I would keep a back up of the two .ini files in BIS; that way you can always copy them back on to the sd or cf card. Also, well worth it to follow the directions in creating the CAB file to reinstall the s/w without the need for the install cd. In case you ever need to hard reset or re-install the s/w, this makes it easy. :approve:
I tried OCN5 but didn't like it much since there are no street names in 3D mode, among other things. I kept getting the Memory Allocation errors since I made the BIG mistake of getting the BIG seamless USA/Canada map with it. You need a MINIMUM of 20MB of free PROGRAM memory to avoid the errors when using the BIG seamless maps. Using this map makes map navigation ( ie. searching for points on the map ) VERY, VERY slow. It took well over a minute sometimes to zoom into a particular place if it was packed with POIs. I am using TT5 now and it is MUCH faster since it only uses regional or state maps, which is a drawback if you are traveling cross-country.
I had OCN5 installed on a 4GB A-Data SD card along with the 1GB US map.
Just another update. I've been experimenting with different install locations and different flash cards for map storage. I've also been testing on two different devices (a temporary privelege being a beta tester)
Here are my results-
#1 Put maps on a fast memory card.
No matter where you install your program, this is the absolute most important speed enhancement, especially running the large XL or XXL maps.
For my devices, an Axim X50v and a iPAQ h2215, the fastest card is an A-Data 2GB SD Card 50X (not the 150X, which is significantly slower in these PDAs). Right now (as of posting time) you can get it for $50 shipped.
I've been recommending this particular card, and all the feedback I get from those that bought it is positive.
#2 Once #1 is accomplished, install OCN to the most reliable place.
A. If you have lots of free RAM, your best install location is main memory. However, if you have your RAM full of programs/data and cannot free up more than enough RAM**, choose another location B or C below.
** In rough numbers:
25MB for QVGA and regional map,
30MB for QVGA and XL or XXL map.
30MB for VGA and regional map,
35MB for VGA and XL or XXL map.
where
QVGA= 240x320 screen resolution.
VGA=480x640 screen resolution.
NOTE: Add 10MB if you are using Windows Mobile 2003 operating system, to account for the storage RAM used installing the program.
B. (Non-WM5 users only) If you are using the XL or XXL maps, and/or do not have enough free RAM, your best install location would be on-board flash ROM ("Built-in storage" or "iPAQ File Store", etc.). These memory locations may be slightly slower for start-up than the SD card from #1, however the difference is minimal enough for me. And there is less chance of prefs.ini corruption in my estimation. (For WM5, the main memory installation location is this ROM.)
C. If you do not have significantly large on-board flash ROM (as in my h2215), and not enough RAM as previously stated, the best location would be the fast SD card where you have your maps.
Please note, if OCN is installed on a storage card, you must be very patient when turning off your device after exiting OCN. Give the program time to release memory and write your pref.ini, even though you have the today screen visibile!

I can attest to the memory card problem. I got a great deal on a travel trailer a few weeks ago, but it was in Arizona and I live in Missouri. No problems on the way down. I got to the lot and wanted to see the trailer, so I powered down the X50v the second OCN exited. Big mistake, because when I was ready to go home it would not work and I had to do a re-install when I got home. Luckily I only took a couple highways plus my brother-in-law lives in Albuquerque, NM so I had no problems finding my way home.
I have installed OCN in main memory, BIS, CF and SD. Except the above problem this one time, I have never had a problem with any location. It is also a good idea to get a fairly fast card to put the map on. I noticed it did much better when I moved from a normal SD card to a high speed CF card.
I did that with OCN4, but I never had a single problem with the program. When I installed OCN5, I decided to not mess with it. Of course then old Muphy's Law got me. I now have it all set up again, so if I have a problem I can solve it. I have a feeling I will not need it again though.
