Just installed the D3, bluetooth, XM, and iPOD cord in my '01 Pathfinder. Put a couple of photos here for you to see if you'd like. A few notes:
Bought radio and parts online, got a better deal than in a 4-hour drive from where I live. I also got a really good deal installing the D3 from HappyEar in Watertown NY (I'm not advertising, they just did a good job). They even installed a lockout switch for the bypass without me even asking. Great job.
The Bluetooth (BTB100) works fine. I had to adjust the volume on my phone a bit, but the location (see photo) in the dash is actually pretty good. Passenger won't be able to talk very well, but I'm mainly concerned with my ability to talk. Reception during several phonecalls was perfect and no echo reduction needed. When you install several add-ons from Pioneer, you daisy-chain them together using the BUS-cords and in/out ports on the back. The tech said that it's a very simple design and it now proves itself.
The XM worked flawlessly as well. iPOD cord is really long, but I just coiled it back into the dash behind the glove-box. As soon as my wife plugged her iPOD into the dash, it recognized it instantly and she was able to play podcasts, video (had to turn on "video out" on the iPOD first) and music perfectly. Great built-in seamless integration. Haven't tried my Nano yet, but that's next.
About the background...first--thanks to those who've posted backgrounds on the Custom Background forum. Really appreciate it! I had a bit of trouble getting the D3 to recognize the disk initially, but after reading about 10 threads about doing it, I found that I didn't "close the disk" for any CD-ROM device to read. Used plain Roxio CD Creator and once I closed the disk...perfect integration. By the way, if you're looking for info on putting in a new background, use tjdehya's post on Mon Aug 14 in the thread announcing how to make backgrounds...very helpful and right on target for the D3 although it wasn't out when he posted his reply.
Okay, that's all. Thanks for all the help. Great forum and great advice.
