Remote controller for GPS103B,TK103B,GPS106B,C,GPS107B,C,Best quality

It looks very nice, has a high quality feel to it, the buttons are firm to press and the sliding cover makes it impossible for any buttons to be pressed accidentally in your pocket as in the cheap-looking original remote where buttons are bulging out and are rubbery which makes sliding that remote into ur pocket impractical and the buttons are not firm so they get pressed easily when you sit down with it in your pocket.However I was never able to bind an additional remote to my TK 103B+, the instructions I received by the supplier did not work and it fails to go into learning mode when the SOS button is pressed 7 times. Hope I find the right instructions somehow somedsy.
