My HB is a 999ci HD. It came with version 7.450 preloaded on it. My I-pilot came from Minnkota with version 2.140 on it. According to the directions from HB, I loaded the new version 7.650 onto the 999 unit first. After the download, the I-pilot link quit connecting to the HB unit.
After deploying the motor about 7 or 8 times it did finally connect to the HB unit. Once it connected the remote for the trolling motor indicated the motor was not found. It took 2 attempts to get the motor to "learn" and the remote is now communicating with the motor.
I inserted the SD card with the new 2.150 version software in the HB unit. After waiting about 5 minutes the I-pilot did not detect the new software. I tried using the remote to search for new software and it indicates no new software found.
Have checked the SD card on the computer and it does have the software on it. I deleted the software from the card and downloaded it again. Repeated all the above steps to no avail.
TOO MANY BUGS!!!!!! I am pretty computer savvy. I have double-checked all my electrical connections and they are good. This product would be impossible for some of the "old timers" to use.
