but u said you're thinking to buy either MTbox or griffin and that's why I
limited my answer to those two!  griffin does not support other models
unless you add (more $$$) software to it and I haven't seen any updates for
griffin in months...  UFS ot twister or tornado (all the same)  are
impressive boxes, now those can do multi brand and they are very stable ( I
use twister)  but to keep getting updates u need HWK  ( I never bought HWK
myself because they had a problem with the twister distributor and started
cheating each other so I bought other boxes)
