Location: Stevens Point, WI | Sorno, I'd do the updates, it's well worth it. The 334 has the internal antennae. I'm sure you've already read, but this link provides you all the changes with the 1.7 version on the bottom of the page. The 1.7 update has been out since 07', all the quirks if there was any should be worked out.

On the older units such as the LMS-334, the older LCX units like the 18,19,20,21 and a few others, don't use anything larger than a 1 gig card. I use one that I use in my Nikon, just make sure it's cleared off. Once you get the update on the card, simply turn your unit off, put the chip in, and power the unit, it will or should update automatically.
If you have any questions, give me a shout, or ask Pointerpride, I walked him through how to update one of your units at the office last summer. |
