well i went and looked at my accessory menu. and it says for th 957 that the interlink is on but the gps isnt. and the 997 says interlink is on along with gps temperature etc. so im thinking theres an option on there to switch to external gps. i remember seein it before and turnd it on. but it shut off or i shut it off or something. but anyhow now i cant find it. anybody know where its located?
