I just finished hardwiring my nuvi 360 and valentine one last night. Everything works great and it looks so much better without any cables dangling to the 12V socket. Here are some pics of the install and I can get more if anybody wants em.
I have my V1 to the left of the rearview mirror. I kinda thought putting it above the mirror would decrease its performance since it has to go through that black stuff on the windshield. Have you noticed whether it works as good or not?
