Hey all, I recently bought a 2016 Citroen C4 from its original owner — an older lady who I don't think ever bothered with software updates. So I'm guessing everything (infotainment, nav maps, etc.) is still running whatever it shipped with from the factory. Any tips from people who've done this on a C4 (or similar Citroen/PSA model) would be great. Thanks!
