Re: Nav IV with Intercom
I went through this headache! I have a 2008 K1200LT w Nav 3 (I think it was the 3) and sure enough the voice prompts from the Nav worked, as did the CB Radio through the Helmet---both transmit and receive).
Nonetheless, I ran into the same brickwall---I could receive a cell call but not transmit.
The dealer took a whole month to get BMW to tell them that this was for communications to a bluetooth helmet--not a wired one. I went ballistic and started a lawsuit against BMW, wherein I had to also sue the dealer since they took the money.
The dealer, "Wild West Honda of Houston, Texas" listened to me and summarily gave me the original purchase price back---16 months after I bought the BMW Navigator!!
I will buy from them, but not BMW.
Do not let BMW tell you it's Garmins fault-they are very helpful!! BMW was just a pain in the south end---and as your post indicates they are still blowing smoke.
I never did understand why they don't put some disclaimer in their catalog that the bluetooth only works with bluetooth helmets.
As you seem reasonable, any reasonable person would assume that since the Navigator ties into the pre-wired BMW Intercom that it would allow transmit annd receive to a wired helmet--- else why buy it?
In actuality, much better non BMW branded units are available for far less and have much better displays and functionality.
In addition, be on the lookout for breaks in their mickey mouse wiring harness (chinese built) as it egresses the tupperware and connects to your Navigator.
