Im needing to get a new radio/ infotainment system. Any suggestions on what kind, I've never had to make these decisions before, im newly divorced. So now i can do what I want, but know nothing about this kind of stuff.
Haven't bothered to replace mine. I still use my phone. I prefer it because my phone mount sits higher and keeps my eyes up level with the windshield.
I believe yours can be upgraded. There's hardware (the pim electronics behind and attached physically to the 8" screen.) It will also require programming of the car's computer. I do not know if the computer in a 2015 will support anything beyond Sync 3.
You can go entirely aftermarket too. That sometimes comes with compromises, depending on whether you also replace the amplifers or continue to use the factory amps.
You gotta spend some money either way. The pim hardware mentioned above is more than $1000 new, I believe. If you can only go up to Sync 3, new may not be available, and then you are getting it from a salvage vehicle.
I'm sure more folks will chime in with more - and better - information and background. What I have here is what I know, and might be outdated now.
