I suspect something is not right with my HDS8 or the software update is not right. To Be Continued.įirst want to thank you and all who have gone out of their way to help me out. Par for the course and reality with differing operating systems. The positives from this thread is I hope anyone else considering switching between these two companies they learn from my experience. It was the only non-high speed card they had left. Gary, I'll PM you my email address and yes I'll take those two files!!! I'm going down below and boot my Mac in Windows XP mode and try to down load process from Lowrance and copy to the 2GB PNY card. They now only carry ultra high speed cards with exception of two 2GB PNY cards. That sounds odd but it is what I was told. He said I needed to get traditional Sandisk Cards and I'd be good to go. He emphatically said Ultra High Speed SD cards will NOT WORK or be recognized by LOWRANCE HDS units. Now I need confirmation from some of you Lowrance HDS owners out there regarding Lowrance CS rep comments and Ultra High Speed SD Cards. Once you put it in that Sonar/Graph it becomes a slave to that unit. You can buy any off the shelf Navionics hotmaps SD card and it will work in any machine. All the same impressive that coming from close to evangelical HB user. I guess the internet scare got the best of me or Lowrance has stepped up their game or combination of both. You'd think Navionics would have a linient trade in program brand switching rebels.Ĭalled Lowrance CS again and by chance got the same person. No shot taken at Lowrance but sure have my thoughts about Navonics. Lot's of hidden gremlins I was not prepared for. It's a shame that I have a Hotmaps Platinum, Hotmaps Premium and Hotmaps South and none of the will work with my HDS. No comments from the peanut gallery.Īlso, I sure do not want to spend money for Navionics card and find out it does not work my HDS.īack on Navionics. For being tech oriented for last 20 plus years I feel very dumb right now.

I do not get any prompts to update my HDS8. When I start up my HDS8 it still will not read that my SD card. Went back to Mac OSX and copied the specific files per Lowrance Download instructions for the Mac OSX. Even went the route and booted up my Mac in Window XP to format my 8GB high speed card. I formated my SD card several different ways.
