Sorry the '18 JGC version is not part of the sale, just the '16-'17 JGC. The '18 and '19 versions that plug in under the seat cost us MUCH more to build.
I understand about the under the seat module for the 2018+. It also makes it harder for us to install or temporarily remove if we have to take our GC in for service at the dealer to not risk warranty issues. If you would offer a little discount off the regular $129.95 price you might sell more of them during this Black Friday sale.
As it is, it's not that big of a deal for me to press the button when I have to grab the gear selector lever that's just an inch or two in front of it anyway. However, I might be motivated to buy this if there's a bit of a Black Friday sale going on.
