No doubt--failure to purchase a rig with Remote Proximate Keyless Entry has been one of the bigger forum regrets.@jeme
That subscription, I believe is somewhere around $200 + per year.

Don't consider anything but the 8.4 with the Alpine . It's offered as Electronic Infotainment System Group at approx. $1400+-.
Also, you will kick yourself in the butt so to speak if you do not get the tow package as with that you get the very very much desired Auxiliary Switches. Many regret not getting this option.
Another big , most wanted , wish I had gotten favorite, is the LED package.
Another big, most wanted, wish I had gotten is the Remore Proxmity Keyless Entry .
You're in Florida so you don't need the Cold Weather Group which is another many wish they had gotten.
As for things forced on you when you order.... that is sometimes the case.
