I have the DS3 Crossback electric, a spec which comes with the nav. I don’t know if the Peugeot is the same, being part of the PSA group, but there are some other advantages of the nav, if this is the case. I’ve just got Connected Nav working on mine, 3 years free from sale. This provides real-time traffic info, speed cameras, weather, car park info, EV charging points and other choices via linked TomTom options within the nav package.
If the Peogeot offers the same connected nav options it would be a shame for you to miss out on them.
