what is on this hard drive?

I get that, but trim is usually for high IOP
workloads with multiple read and writes. For an SSD drive in car used for navigation I fully expect it to be 99.9% read only with only minimal data writes for user metadata such as stored destinations etc.

I would also comment that a spinning traditional hdd has more chance of failure in a car than an SSD drive regardless of flash fatigue.
I tend to agree with you - but had a customer with a NTG3 that had read somewhere if you go SSD in that it doesn't last long. But its not something I have tried.
 
Mercedes still use Hard Disks in the new nav systems (well, I've checked NTG6 but not NTG7). If its cheaper and they'll work for the length of the warranty, that's what they'll use. Interestingly theres a lot of NTG6 hard disk failures at the moment - but I suspect the manafacturer of that HDD is paying for their early failures ...
