Sawyerghost,
If you plan to add CB, XM, NIM, Ipod interface, etc., go with the 77108-09 kit since all of those use the NUOH. It lists for $379 ($20 less than the 77107-09 kit) but you'll need the NUOH that lists for $129 and you'll probably be charged for the intercom flash since it's not included with the 77108-09 kit as it is with the 77107-09 kit. If you use the 77107-09 kit now, and later decide to add XM, NIM, etc., you'll probably find that the harness included in that kit will need to be modified to use these other devices that are intended for use with the NUOH.
Said another way, if you want to maintain flexibility to easily add the other audio accessories (CB, XM, NIM, etc.), go with the 77108-09 kit, buy/use the NUOH, and adding the other audio accessories will be plug and play; trying to add these to the 77107-09 kit will not be plug and play.
