Interesting post as I was going to ask what system would people recommend. The website you posted is in Thai but Im not to sure if they can help with my Toyota being 2009 model. I also couldnt see any info about price so I will let my gf take a look at it as she is thai.
The only other place I have come across so far that offers this service is this place:-

It looks like a quality installation place and the price isnt too bad approx 40,000 baht, the local thai mechanic quoted a price of around 30,000 baht but I dont know what equipment they would use. I will welcome any views, opinioons or insights
Cheers
