<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Can you be more specific? I have multiple GPS 18 units and even one GPS 18x running, with some of them attached to D700s and I've never had a problem. The only issue that I've heard about is that the very early GPS 18x units (the 18x is the high-sensitivity replacement for the now or soon to be discontinued GPS 18) had an altitude limit in that they would no longer report altitudes if the unit went above 60,000 feet, but that issue was resolved with a firmware upgrade several months ago. I just looked at Scott's page and it still mentions this bug, but that page is outdated since the bug has been fixed. Even if you have one of the early GPS 18x units you can upgrade the firmware which is available at garmin.com.<br><br>I've had nothing but excellent results with both the GPS 18x and the older GPS 18. I'd highly recommend using the
GPS 18x. It's been reliable and has very fast acquisition.<br><br>-Jerome, W0JRT<br><br>--- On <b>Sat, 1/24/09, Rich Garcia <i><k4gpsc@gmail.com></i></b> wrote:<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"><pre>Scott's web page and it seems Garmin has a problem currently with the GPS18<br><br></pre></blockquote></td></tr></table><br>
