blm user here...since 2008
currently everything is stock, maintained & working well , except for the head unit... upgraded to another model that supports mp3

compared to my previous iswara, the monthly payment & periodical expenditure is stable, no more 'suprise' repairs here and there...
after all, i just want a car that is able to serve its purpose...

i just poke a small hole via the rubber seal that sits between the door panel.
make sure it is small enough just nice to fit in the wires...don't want any water leaks in there..

i use a small tip soldering gun to make the hole, other accessories shop just prick it with a sharp object....
