Many have said the 2019 and up already have the GPS antenna, if you add Sirius, is the antenna already equipped for it too?

Bumping this..when I look at part numbers, it always says antenna, gps, satellite. I want to upgrade, and wonder if I need to change out the antenna to add satellite. Anyone know? From a part listing, I’d guess no, but want to make sure. Thanks!

My 20 did not have the satellite antenna.

Installed 4" to 8" Screen Upgrade. The stock USB hub in my 2020 base works with the new system. Now I need to get the Drive Mode switch working.

Thanks for all the good info in this thread.

I assumed as much. How about 'auto' mode. Does that work?

Yes auto mode should work. The base climate control is already operated electronically.

Ice does installing this change any of my other Forscan adjustments, such as EQ bass roll-off.

Not sure, maybe. I don't know if those changes are in the BCM or APIM

I did my 4” to 8” upgrade yesterday in my driveway. For me, the hardest part was taking apart the dash. Everything works great and I have the toggle switches programmed for drive modes too through Forscan.

Thanks to members here, esp IndyRN for all the good pointers! mine is a 2019, I wanted to add a CD player, but several said programming may be an issue, so that’s the only thing I didn’t do that I originally wanted. I added factory nav, HD radio, and satellite too.

Thanks for clarifying. Ill post as soon as i get mine installed.

Installed this morning. Parts from a 2019 gt bezel apim and acm that i got off ebay. Plug and play and took about 45 minuets to install and program with forscan. Works great.
