I've encountered the same problem with my Venture HC. I've tried at least a dozen times in the last three months to update and the software updates, but the chipset won't. I contacted the Garmin technical support about it and they thought it was my firewall, but after letting them log on to my computer and shut off all the security programs, it still didn't update. They also checked the data transmission to and from my Venture to their website and said eveything is working fine. They now think the problem is that I already have the most recent update. I guess I'll have to wait for them to post an update to verify that. Phynd
