someone write a review say this do not work in they Scion xb . I purchase this for use in 2008 Scion xb with the factory upgrade stereo -lrb- the one with the animated graphic -rrb- . installation work fine for I and it fit my Samsung Droid Charge in a Otterbox case . you 'll have to remove the bottom bracket and slide you charge down a bit to use the micro usb port when it be in the Mountek . it do not fit my TomTom XL 340s gp by itself . it may fit if you attach the factory supply suction ring to the back and use that for the Mountek to hold onto , but I no longer have that and therefore could not test it out .
