I have a XL330S (aka ONE XL v9). Tried upgrades to navcore 9.026 and 9.051 to get support for IQR and ALG. Beside a slowdown in speed (which is understandable with that hardware) there is a MAJOR downer regarding the computerized voices (VocalizerTTS), especially the non-US ones (French in this case) which spell text instead of pronouncing it.
According to info on TomTom website ([Please Register or Login to download file] ), that bug should have been fixed in v9.024 onward.
Has anyone noticed the same problem and be able to fix it?
