Hello is there an IGO8 version correcting the 6 April 2019 bug ??? (for old GPS)
Thanks for any answer.

No bug for me.

Did you find a fix for this.
i've got three wince 6 sat navs with igo8.3 and they're all doing the same.
time clock is unstable.

You could try updating to primo. I have a chinese unit that has installed on it primo and a early version of igo. The primo works perfectly but the igo has the same problem as yours, indicating it is a problem with the software and not the unit
