I always thought POI Explorer is the only way to add custom POIs to Mio C230. I just found out a feature of C230. Adding custom POIs is so easy.
- Find the POI set from the sites like POIfriend.com .
- Download the POI set in Google Earth format (kml).
- Create a folder called POI in the storage card.
- Copy the kml file to the POI directory.
That’s it. No lengthy conversion is needed.
I just tried the other Google Earth format (kmz), and it works too. The kmz is a zip file of kml. The file size is much smaller, 3 KB vs 37 KB for a 10 POIs file. You can use Google Earth to manage your POIs.
My reader reported that after adding custom POIs, the machine becomes sluggish. I also noticed that myself. So far, I only added 1564 Target POIs and when I type something in the POI search screen, there is a slight delay.
I decided to give POI Explorer a try. The internal custom POI file is called iGo.db in the MioMap folder (or MioMap2 if you use my hack). You can use POI Explorer to import from and export to this file. When I am done importing the Target POIs, I then exported the POIs to the original iGo.db. The exporting took a long time, about 20 minutes on my Acer Ferrari 3400. The original iGo.db file is 70KB. It’s now 392 KB after I added the additional 1564 POIs.
After so much trouble, you would think the performance would be better, right? Unfortunately, I didn’t notice any improvement over the previous method. Actually, the startup takes a longer time to load. I think I am going to stick to the straight kml or kmz download for now and load only the POIs I really need.
A reader has asked for a quick run down for POI Explorer. Note that I found that POI Explorer is very buggy and it crashes a lot. I don’t recommend that you go this route. Anyway, here are the steps:
- Download and install POI Explorer.
- Turn on your Mio C230 and connect it to the computer using a USB cable.
- Mio C230 shows up as F: drive.
- Have your iGo.db file ready. It’s in F:MioMapMioMap or F:MioMapMioMap2 if you have unlocked it. Make a copy first, just in case something goes wrong.
- Run POI Explorer and click on File -> Import -> From iGo database from file (offline)… and select the iGo.db file from your unit.
- On POI Explorer, click on File -> Import -> POI from file… and select your downloaded POI file in csv format. Note that I tried kml files but POI Explorer crashed.
- (Optional) If you want to change the icons, you can do so by first selecting the POIs and right click and you can change icon. However, the icons are limited to the default icons. I don’t think you can use other icons.
- Click and select the folder and drag it under “iGO POI Database”.
- Repeat the steps 6 to 8 for all the POI files you downloaded.
- Click on File -> Export -> iGo database to file (offline)… and select the iGo.db file in step 4 or a backup of the iGo.db file. Note that this step takes a long long time. You might want to do something else in the mean time (like donating to this site 😉 ).
- When the process is done. Copy the iGo.db back to the original folder.
