This device is sold at some of the shop in low yat... it cost around 100+
anyone using this device??... how it works?

thanks for sharing guys... i'm thinking of using the device with a thumb drive.. so i think i have to buy a thumb drive and the FM modulator together.. it's better to use this device because you can use it on other car.. unlike cd player which only can be use on the same particular car.. hehe

thanks!
