some people have no idea what they are talking about (as they don't have experience and never done it) so think for yourself
my 1998 lexus has a built in hard drive for gps, its almost 20 years old , and we almost minus 40c (Canada)- I don't even store the car in the garage and the GPS still works fine . its a Fujistu hard drive I believe. the temperature of the car inside warms up quicly too when running. .
now also by chance, Im a news van operator, we have computers mounted on a rack, the hard drives are from 2003 , and they are just also Fujistu drives. they still run fine,
just don't waste your time money buying a disposable drive (Seagate and many entry WD) for example.. get a server drive, a made in Japan drive just something that is known for reliability.
