I have searched around and have not found a conclusive answer to my question. I have seen a few older 656 for sale that are listed as antimagnetic per DIN 8309 (4800 A/m) but I know the newer models have a very high rating, 80000 A/m. So my question is, do all model 656 have the same higher rating or just the more recent ones? Specifically I have seen some special models such as the Mazda 5 edition that is listed as a model 656 but don't list the rating. Thanks in advance.
