so what else i can do to make garmin with no lag ??

PS: external GPS turn it off ?? set it at none none none ?? is it that bad??

2 seconds isn't all that much time walking or driving. You sure the lag isn't more than 2 seconds to be a problem.
If there is something that is showing you a "Report every 2 seconds" ignore it. Most GPS reporting is set to 1 second. So 2 seconds is not that bad. If you were using COM4 you will get way more lag than 2 seconds and it becomes unusable. Try driving with it set to Intermediate Driver and think you will find it works fine. I suspect the report every 2 seconds your seeing is the Garmin app itself. And 2 seconds is normally fine.

I'm not sure how to turn "External GPS" off, as long as NO application is use that COM port it should not be impacting you.
