I have had a Pioneer Avic D6 in my sequoia for a couple of years. I fought and fought with the installation and got it done ok, but could never bypass the safety features. I finally just accepted that there would be no video. I can live with that. But the thing that just torqued me, is that you can not even type in an address in the nav, or do a regional poi search. When you are moving, it all greys out. So, I have to pull over to type into the nav......If I am going to pull over, I can pull out a freaking map!!! That pissed me off. Besides, the nav is far from accurate. So, after all that time, I am selling the Pioneer. I just installed a Kenwood DNX7140. Holy cow! Super easy installation! Safety bypass is a no-brainer! The nav (which is by garmin) is dead-on. Even the touch screen is much more responsive. Please, take it from my experience. Do NOT get sucked into the lower price of the Pioneer. I fell for it and paid in the long run. It is NOT worth the trouble!!!!!!!!!!!!!!!!!
