OK, if it worked.

Didn't fit an 07 Accord with Navi. Contacted Bazooka support, they acknowledge the fitments issue as others on their forums had similar problems with other vehicles. I had plan to use it as a T harness for a project since this harness has a pin to pin connection. If you purchase a metra or similar harness for aftermarket radio hookup, you will notice that only neccessary wires are used, therefore you lose navi voice prompts. I used the Metra BT-1721A instead, more expensive but works great for my project, plus you can hook up a aftermarket radio and KEEP voice prompts.

Did not fit into my Honda 2002 EX OEM stereo

Not sure why it says this is for 1998 and up but when I ripped my console apart and tried to fit it in the hole the 1721 adapter was too big for the back of the stereo. The other end fit perfect. I tried to modify the adapter to make it fit into the stereo but no luck.
- Simply put this does not work for all 1998 and up Honda so be aware.
- I ended up using the 9999 adapter and splicing it into the wires. (I was trying to avoid doing that)
