this be a device for the person who like to get into the inside of the system -lrb- I believe its call hacking -rrb- . for such a person , the device be great . I would not recommend it for a novice . here 's why : 1 . the text to voice pronunciation be terrible . the word run together , for example , ` San Jose ' be pronounced sanozay , San Francisco sound like ` sunfrincisco ' . now , the interesting bit be that this issue can easily be fix by someone who can hack into the system and make a few small tweak . I wonder why TomTom can not just do be in the device they ship out , or as a software update to those already sell . 2 . this device - 540 World Traveler Edition - be pitch as have complete US , Canada , Mexico and Europe map . truth be , this gp do not have room for the newest version of these map . you can have all of North America , but not all Europe , only bit of it . for example , you can have Western Europe , but then you can not have southern Europe - because there be not room on the device to accommodate that particular map . same thing for Eastern or Central Europe . this would not be such a big deal if you could be selective about which N. AM . country map you need , so you could leave out Canada , or Mexico or US , and make room for all of Europe . but you can not do that . 3 . the worst thing be that it take age to upload map , or swap out between the regionsl european pap . we be talk hour . if I be to travel to Europe , I would therefore have to lug along my laptop and flip map back and forth every time I want to go from , say , the UK to Italy , or from Sweden to the Czech Republic . and wait around for a few hour while the GPS sit around upload the right map . I think that if TomTom do not fix the map problem within a reasonable time , I will probably send it back , since the device do not function as advertise . have say all that , once you hack it and set it up properly , it work well -lrb- except for the map problem -rrb- .
