Hi All
I'm still waiting for the SG11 and interface unit to be available. From my conversation with Ron at SG, it maynot be ready till the end of September now. They had to increase the size of memory (64MB SD), but I think they may also be trying to fix the problems most people are having now with the first SG11. It sounds to me like a program problem and you may be able to go on line to a site to download a fix real soon. Don't know this for sure, but the girl that answered the phone at SG said upgrades should be available over the internet soon.
My suggestion is call Ron at
http://scangauge.com/contactus.shtml and tell him what your problem is, and let him advise you what to do.
Also, Ron told me to send an e-mail to get on a list if your want to be notified when the interface is available. They will put your e-mail in a folder and send everyone a message back when they know the date. It looks like the interface will be an additional $99 according to Ron.
My original SG only had one problem due to being in direct sunlight. I placed a insulated cover on top of it, and it's worked fine ever since.
Good Luck with yours.
