I don't know if the pins exist at the back of the newer EHU/ICM combo units like they are on the 2003-2006 EHU's. Since you have built-in aux via the 1/8" stereo jack, I would guess not.jfc686 said:I'm trying to see if there is some connection that I can make for an auxilary input rather than the 1/8" plug on the front. I have a nuvi 660 and the fm modulator built in is too weak so, I connected an external fm modulator to the headphone output on the nuvi but, there is still alot of static so, I was going to see if there was an alternate input.
