Plan on helping a friend install a 998 HB tomorrow. I have downloaded and read the entire manual so I have a fair understanding of the installation and some of the operations of the unit. I was wondering if there was any other items that we might need for the installation. I think that I will need the following...

in-line fuselink and a 3 amp fuse

an SD card but I'm not sure what kind

I'm pretty sure that he didn't get the map chip so what do we need for Arkansas?

18 gauge red and black wire

If anybody has any suggestions please let me know.
