RTI Navi Software / Voices / Language…

Was there a new V70 for trial driving (hardly excited) and I noticed that the voices (woman/man) in the Navi were different or sounded “cleaner” or “expressed” more understandablely than it is known from my V50 RTI. Didn’t update my software/DVD so far because I don’t have the Navi soo often in operation. However, I’ve always been disturbed by the cumbersome, “puzzled” way of expression. Completely hacked off and also often wrong in the sentence making (“please keep them on…” etc.) because the way is taught… Sometimes the voice also gets “dumpier” in the middle of the sentence and it sounds like suddenly someone else is speaking. In addition, the female voice is completely useless because it sounds like it has been recorded under drug influence… Well – these things may already be known to some here…. That was not all so in the V70, and therefore my question whether these errors in the V50 are also “excessive” with new navigation software, or if only the card material is updated here? Did anyone have noticed a serious difference in language?
