after market JK CD player

[SCORPIO]

truck : JK 2016 sport

stock CD player do not support Bluetooth telephone and music,
i need an aftermarket one to support the same, GPS is a plus

question :

if not whats the required size ?
any recommended specific unit ? supplier or shop ?

and yes, i still HATE Jeeps, but this have to be a gift that's why
i'm collecting information to get the right item once for all


thanks
