I have a 08 SE with the base model radio in it. I am looking to getting a unit of a fellow memeber and it is coming out of a 07 and I think i read some where the wiring harness is different between the 07 and 08.
so your buying an aftermarket radio and NOT another factory radio, correct? if so, then you just need the 07 and up harness. the frontier didnt change harness plugs till 08 where other nissan models changed in 07.
all you need to do then is buy the adapter for your truck then snip off the adapter from the 07 and wire it up. make sure you leave yourself plenty of slack in the wire when you cut it. and as SND said you will need an antenna adapter.
