Speaking of &quot;Betty Lou&quot;, I have a built-in Nav system.  But, I&#39;m going to buy a portable unit prior to our trip back to New Jersey and Florida in May.  Want to use it in our rental cars.  Never been so lost in my life as I was with Roe navigating us around her home area of Northern New Jersey&#33;&#33;  Planning on getting one with European navigation maps as well for our 2010 trip to Europe.<br /><br />Later,<br /><br />
