aftermarket stereo,

[gitchies]

So i go to a shop to get my deck installed today...and no go....

i have factory nav with the cd changer in the trunk. i didn't think i had a factory amp, but turns out i do?

they order me all the parts i need, the bracket, harness and antenna...upon taking out the factory unit, they find the harness is totally off from what they had ordered me....strange? they say they can't do it, call metra for tech support...they say it can't work...with what they have? so prob have to order new harness? how difficult is this? I need some input from everyone here......

all i want is deck to support my ipod touch, i dont care for nav...but man this seems like a nightmare for audio installs...i even look myself at the harness in the factory unit...its soo small, and the harness that was ordered looks huge....the shop is even like in ah?
