Author Topic:   Garmin GPSMAP 430SX Upgrade

I recently purchased a Garmin 430SX. This is the Sounder, version with XM satellite weather and fresh water (inland) lake maps. It came with the version 2.x of firmware. Garmin has published a recent update, version 4.2. The Garmin unit is updated via an SD card. The update file is easy to download from the Garmin website. I was unable to locate any installation instructions. When the downloaded file is executed, it places the updated 430SX file in a directory on the SD card titled “Garmin”. The SD is then installed in the unit. I fooled around for a while trying to get the Garmin to access the SD card without a successful update. Initially, I tried with the SD card installed in the Garmin when it was first powered on. Nothing happened, just the standard GPS startup screen. I searched the menus, nothing. Finally, it occurred to me that the Garmin might not recognize my 4GB SD card. I searched around and found an older 2GB SD card. The update file was again placed in a folder labeled Garmin on the smaller 2G card. I placed it in the 430SX and powered it up. Voila, I was provided with a new menu, it was the update menu. From here, it is easy, and in about another 15 minutes it was finished updating.
Some points of use, this unit is bright, and is very visible in sunlight. It is warm to the touch when operating. Operating speed is much faster than my old sounder, a Garmin model GPSMAP 168. I originally wanted a larger screen, but the family budget prevailed. While small, it is very usable if installed within arm’s length of the captain.

A 4G (and up) SD card is SDHC (Secure Digital, High Capacity),
not SD. It's a bit different electrical interfrace, and LOTS
of things that work with SD won't work with SDHC.

Thanks for your comments Chuck.

Instructions; Yes, but those are the instructions for the download and install to the SD card only. They do not mention the update procedure of the Garmin unit.

SDHC; Yes I am aware of the difference, and (wrongly) assumed that Garmin would use hardware compatible with the current standards. The SDHC cards became industry standards a couple of years ago, available in various speed (or data transfer ratings simply referred to as class ratings). Interestingly, they list system requirements and do not mention their incompatibility with SDHC memory. This is quite unusual, as they have current hardware in other consumer contact areas; for example the XM connection is mini USB, the small bright display screen, etc. Overall a nice unit, flawed only by the incomplete documentation. Now let’s see, is my transducer a multi beam or multi frequency. Don’t know…

SuburbanBoy--You unit can now read SDHC 2 gigs cards and above. It was part of software update v 4.00 for that was made when you updated your unit to v 4.20. To see what was changed and added by each update use the Garmin link below.

Thanks BWP, unfortunately, I was at ver. 2.2 or so... Therefore I was unable to make use of this feature until after the update. I would be shocked if there are additional updates for this series. The 400 series are a good value and useful in full sunlight. My next unit (in five years) will probably be XGA and 10" in size and updated with a USB key. I will report back about the XM weather feature later. Great weather in South Haven Michigan right now, but this will not last for long.
