Why can't you get after-sales support from other suppliers?

We got many email or message about after sale service from the buyers who didn't buy Car DVD Players from us,so strange?

Some of them ask for details of operation,some of them ask for replacement because of the mistake of car dvd player model for his car,some of them ask for software upgrade,some of them ask for spare part for repair...we'd like to help any one who have questions or problem about the car dvd player,that's why we release our official blog for FAQ.But if they ask more than what we can do in our FAQ blog,that will be a problem:we can not support the ones who didn't pay us.It is a pity but it is true,because the after sale support will cost us many time,even cost us profit.
