I have just purchased a 2005 IS250 Sports Luxury. The navigation system seems very old fashioned compared with the portable GPS's we can purchase today. I have had to recalibrate my position several times (which you never have to do with the portable ones) and my question is, if I upgrade to VER 17 being the latest map, will this fix the problem? Also is Ver 17 just the maps or is there some form of upgrade to the GPS itself? I would hate to spend $350 on the DVD only to find that every time there is a bit of cloud cover I still have to recalibrate my position. It would be a total waste of money if that is the case.
Has anyone else experienced a similar problem and if so did you fix it with a new map or is it the actual system which is just ancient by today's GPS standards?
Thanks
