i think you probably have garmin software....on the sat nav
in which case there is probably a way to pull the product keys out of your US centric sofware and patch them into a map update from Euro/FIAT chrysler Ucoonect/Udrive
radio...well we use DAB and DAB+ the Us doesn't i'd expect it to be a software change but you never know might be a chip that can't be changed that means only FM

if these geezers can do it for 399 Euro you can more or less guarantee that its a case of finding someone willing to tell you how to do it
it won't be a case of it being technically awkward its a case of people who Know how, and people who don't, those that don't. have to pay
you need make and model numbers off the UNIT and then search the net for a person who was willing and able to break and fix their Unit... companies selling this kind of upgrade usually trade on the fact that they found someone who had done all the hard work for free and they nick the idea and charge the rest of us lots because they know how and we don't
that means there will be something somewhere that tells you how, for free
looks like cars VIN is used to generate software keys....
check out their jailbreak products to let you activate options you don't have
