The only place you seemingly can get it online is here:
Jensen Stereo, AM/FM/CD/USB/BT/iPOD/Sirius/Navi
In addition, they are calling it a special order item which makes it take longer to get (and probably has some return restrictions).
If you download the owners manual (like from here:
http://www.jensenmarinedirect.com/do...ers_manual.pdf ) you see on page 9 that the wire harness (part 31300152) is mentioned as "Sold Separately". Since I haven't received mine yet I don't know if that harness is included or not. I've been scouring the internet for that harness in the event that I have to get it. So far I've found two possible candidates (one on Amazon and one on eBay). I'll know which one is the proper one when the 215 arrives (hopefully within a couple of weeks).
I pulled the 212 out so we're ready for the 215:
(Another unknown is if I have to pull out that collar and install the one that came with the 215--I'm hoping not.)
LOL Sorry to the OP for hijacking the topic...!
