Hi all,
I used HLT on a track day last weekend and it worked great! Showed it to a few at the track day and they purchased it then and there.
I am getting ready to upgrade my iPhone from 4S to whatever Apple will call the next one. I have a GoPoint GL1 (cable version) that I use and don't want to loose that functionality.
So my question is... when I upgrade my phone I will no longer be paying for data on the 4S. The SIM card will be removed. I know I will loose cellular network (preload tracks at home on wifi) but will I loose the functionality of GPS as well?
I could purchase the 30-in to lightning adapter for the GL1 and the new iPhone, but don't know if it will work.
Any advise on either option?

Will HLT work if sim card removed from iPhone 4S

The iPhone will work fine without SIM. I have an iPhone 4 I use without SIM, so it's basically an iPod Touch

I use one an iPhone without a SIM card and my new one as a multicam so if I get a text or call it doesn't interrupt anything on the main timing device.
