These options look fine to me, although I’m no mkgmap expert. Just give it a whirl.
Whirl given 
Takes a while before it’ll be available for download though. The update must finish successfully and I have to adapt the site to add a test version of the generic map.
Thanks Lambertus. I look forward to see the fruits of our combined labours.
Is there a way to install more then one card to for ex. mapsource from openstreetmaps?
If I want to install more then one card it says generic card already exists and deletes that card so I can only see last installed one.
I already tried to rename the map after install with JaVaWa GMTK but that does not work, problem stays the same.
Welcome to the forum, Estate.
[ When you write card you mean map, of course. ] The answer to your question is in the FAQ, which you should read anyway. You need to change the product ID. Changing the name is optional, but useful, otherwise they are all called “OSM Generic”.

Peter.
I see that the last map update was almost three weeks ago.
I was wondering if this project is stopped or if theres a new website?
Thanks
This project certainly hasn’t stopped, updating has been postponed due to a new map being added which happens to be available now
Paging Beddhist @ Ligfietser 
Suggesting I did not read the faq ? well okay, I did read it but clearly not good enough 
I did try what you say here but it does not help maps are alle installed as OSM Generic Routable in Mapsource, which presents a problem offcourse, because I now can not use maps separately.
Reason I need separate maps is that I plan to use it on hollidays when on the move with our mobil home and do not want to get my Garmin cluthered and slow as hell, the second reason is that I normally (with tomtom at least) put all kinds of interesting sights and seeing marks in there so when on the move with our bikes we can easely visit what we want to see.
Is there a really good way to get the maps installed together ? It seems to me that this is the reason lots of users sell their garmins and choose for tomtom, or am I wrong assuming that ?
kind regards, Jan
Have you tried the JaVaWa tool linked in the FAQ to change the product id (and name) of an already installed map? After that you can install a second map. Rinse and repeat to install as many maps as you want…
Edit: Ah, I see you tried changing names, but you need to change product id’s as well (which is even more important then changing the name).
Hmm, somehow the style is not showing in the new test map although a typ file is included.
Yes, they choose for TomTom because it is impossible to put OpenStreetMap maps on a TT; problem solved… 
Installing OSM maps of a larger area is more difficult than installing an official Garmin map; that’s true. But, when you can’t get it to work you can always get a refund…
Oh wait, you didn’t pay anything for it.
I just downloaded the new look Thailand map. Looks good to me here. The typ definitely works. Thanks for all your hard work you continue to put into this. 
As far as I am concerned this is the most useful OSM web site there is.
Now we can continue to fine tune the style.
Q: do we need POIs for areas? Every island gets a POI and there are lakes where the POI is way outside the water due to the crescent shape.
Another project I want to tackle at some point is a routable map optimised for motorcycles. As we all know, the maps can’t distinguish between cars and bikes. There are many places where bikes can go, but not cars and vice versa.
I didnt get anything Lambertus 
Yes we need them but not in all cases. This has to be finetuned. In mkgmap you can exclude it with something like place=* & mkgmap:area2poi!=true [0x… resolution …]
Well, thank you for the work on the stylesheet!
Perhaps, if such a style would exist, I can add this to the site… hint hint
Edit: posts about stylesheet moved to separate topic.
Discussion is moved and I copied the test files to “world” and also added some changes from the latest mkgmap default styles.
Lambertus,
Any idea why this island is not rendered: N14.02267 E99.52300
It seems mapped correctly (I don’t know for sure, it’s a multi-polygon), but in the img file there is a river polygon exactly covering it. I guess that’s an mkgmap bug?
Cheers,
Peter.
The source OSM file is here.
There’s no hint of trouble in the logs:
I don’t know why the island does not render.
Peter, it isnt rendered because of the wrong OSM tags. The inner polygon shouldnt tagged with riverbank but without any tags.
If a polygon tagged with riverbank means inside it will contain water (riverbanks are the outlines of the river), so mgkmap thinks it is a river instead of an island.
http://www.openstreetmap.org/browse/relation/2067334 All inner islands are tagged the wrong way, and those riverbank tags should be removed.
The correct way to tag a river like this, is to put a tag waterway=riverbank on the relation itself (with type=multipolygon), and no tags on inner and outer ways.
Thanks Minko, I should have known that. I fixed it. Can you please check it to make sure I have done it correctly?
