A seller didn't tell me the car's nav was broken. Should I worry about it?

I want to get a good, used Mercedes-Benz B-Class diesel around 6-7 years old. On a test drive, everything was good. Only that the car's sat nav screen doesn't work and the seller didn't know about it. They said they will fix it. Should I worry about this issue in a long term? Can I ask fo the lower price? I want to get a car for things like going for a grocery shopping, dropping the kids off at school etc and I've found searching for a used car exhausting. There are so limited options out there. I want to wait but I also don't know if I will find a car like this one again. Thank you in advance.

The faulty sat nav is a big red flag. The seller would have probably known it was faulty. And he/she should have pointed this out to you (or got it fixed before advertising the car). The fact they said nothing and waited for you to spot it would make me wonder what else might be faulty on the car. I'd recommend finding another car for sale with a more trustworthy seller.
