One Pak allow adding items later?

[TimRF79]

I am fixin to close on a plane with a GTN750.
I will fly it for about a month and then look at adding G3X, GI275, GNC255.

Can i buy a one pak now and add the new stuff later?
Anyone knows?

I upgraded from a GTN650 to an 650xi - no problem adding the device to my onepak. Not exactly the same, but I'm 99% sure it's inclusive of all your Garmin devices.

I’m assuming if the extra stuff costs money, Garmin will allow it.

Called Garmin,
they recommended to buy the subscription for the GTN first, (lower cost).
Then when rest is installed to call them and they give a pro-rated credit towards the OnePak (can't be done over the site).
