Hi, just wondering if anyone can help me, I have a new 788ci and the SD card reader in it does not seem to function? I have tried two different Sanddisk 2Gb cards and the head unit does not seem to register them? When I check the GPS diagostic view there is no card showing? I have an old version of software loaded (4.620) and wish to update and also wish to install a Navionics Gold card but It's not looking good....I guess I can buy a PC cable for the software upgrade but I wont be able to install a decent map!!!
Thanks in advance for any help offered, Darren.
