GPS roads displayed vs scale on trunk mounted unit

Hi, I have a trunk mounted dvd based GPS unit in my trunk mounted 2004 330Ci. One complaint that I have about the GPS system is that when the scale is zoomed out, so few roads are shown on the map. Is there a setting in the programming section that would increase the detail of roads shown at smaller scales? Right now the map at any scale about .5 miles is little more than a general reference. Thanks

Do you have the latest dvd map database? Check out the Wiki on this site for nav programing options.

No, I don't have the lastest maps, but I don't think that will make a difference. It is not so much the updates, it is the number of roads that show at the different scales. I saw that if you go into program mode, there are many options, all in hex code that you can set, but I was afraid to mess with them. I was wondering if any of them related to the level of detail shown on the maps at each scale.

I will check wiki.

Thanks

I looked on wiki, nothing there about the roads shown vs scale. I find the maps relatively useless at a scale smaller than 1/2 mile. I would like to be able to have the display show more roads at the 1, 2.5, 5 mile, etc scales.

Don't know what else to tell ya Khp. I drive an '03 w/mk IV dvd based nav. A few years ago I updated to an '04 database and it had more "stuff" on it (including roads) ie "points of interest". I noted in the wiki that there are aftermarket databases available:" Official map updates are available from BMW dealers, NavTeq (www.navteq.com) and TeleAtlas (www.teleatlas.com). Since non-professional or "HIGH" maps are compatible with the VDO-Dayton "Carin" format, these maps can also be purchased from other vendors that use this format, although they will not have any BMW-specific point of interest information on them." There are a number of "spark chasen wizards" around here that stay up on this stuff. Maybe a guru or two will chime in - good luck with it.
