Once a check routine has run, the IAM can spot errors in the flash memory the navigator uses. The fault is set when the checksums do not match, and It shows up as navigation problems, for example saved locations that cannot be stored or disappear.
Possible causes

- 3If the fault returns after reading and clearing it, have a workshop replace the integrated audio module (IAM)
