Garmin 660 and Dice I-BMW-T Will It Work?
Recently I purchased a Garmin 660 GPS to replace my Garmin 2720 with full knowledge that it was going to be difficult to integrate all the functions that I am used to with the 2720 into the J&M ComSystem I have on my '99 K12LT. The 2720 wired right up using only 3 wires in the OE BMW/J&M to Garmin wiring harnesses and works flawlessly. At any rate, after talking to Garmin about updating the 2720 with new MapSource data I decided to bite the bullet and purchase a newer model. I've been trying to figure out how to integrate the new GPS so that I have the same functionality (or better) with the new 660 and may have inadvertently stumbled onto something today. This afternoon while doing some initial experimenting with the new unit in my truck, I had an epiphany.
Using the 660s 3.5mm audio out port (on the side of the unit) and the 3.5mm aux port on the front of my truck's radio I discovered that I got gps voice directions, a cell phone connection, and MP3 through the truck's speakers. The audio for each also muted in priority for each source - MP3 muted for directions, and both muted for the cell phone. So I got to thinking - would the aux port on my Dice I-BMW-T Silverline (replaces my CD changer) which is also 3.5mm allow me to simply wire the Garmin 660 through the Dice aux port with the same results? I know I'd have to select the proper input through the radio controller/stingray, but would that give me everything I'm getting in the truck? I also realize that as soon as I select AM/FM, WX radio, single CD, etc, etc, that the 660s info would cease to be connected in a usuable way using the Dice connection. The Dice aux is advertised to be able to connect an XM radio, an mp3 player, TV, or any other audio device to the vehicles audio system. Am I missing something? Will the 3.5mm port on the 660s wiring harness provide the same audio as the 3.5mm audio out on the unit's side? I'm one of those dual GPS guys for long hauls, so I'll still have my trusty 2720 mounted as well, with the old tried and true connections, so I shouldn't get too lost or lonely when I need to switch to a single CD or to FM for company.
I don't have the bike with me right now, or I'd be out checking it myself, but would/will this work? Anybody tried this? Pitfalls? BTW, I use and old Nokia cell phone wired to the J&M, so I'm not concerned about Bluetooth cell connections. I'd just like to find a simple solution and not have to cut and splice the 660s monstrous motorcycle wiring harness!
