That is an interesting concern.
Are you planning on bringing your EX in to the dealer anytime in the near future? I would like to take a look at it.
There are a few things I would like to look at. You may have an issue saving a home location but you should be able to cross zones without an issue. I wonder if this has something to do with the NavTraffic software, because I know even the older (like 2.1 old) could go cross country with no logic issues. I know there are a few new software additions we can install in your EX to see if that has any effect on this. There may also be a different way to get it to a cross zone trip.
This does not require purchase of a Nav update coupon. The Navigation software version is not being altered so you do not need a disc or anything at this point.
This type of issue is one of my favorites, if you have some time and are in the area you are more than welcome to stop by and we can take a look at it, instead if speculating.
If you had an older DVD based Nav you know that they needed update discs that needed to be purchased from the supplier. The 07+ models switched to an HDD that runs on an internal hard drive so any updates are run through the Compact Flash drive. There is no need to buy a disc anymore to update the Nav software, you need to purchase a coupon code from
http://www.navigation.com/is-b...u=YES to get a version 8.2 code then we need to run it through our computer and secure website to generate a code that is used to load the update onto your car. The coupons are on sale now so we have been doing a bunch of these and the new version is actually a decent improvement. They have changed the guidance layout slightly to mimic the portable units slightly more.
