Adding Bluetooth audio streaming (A2DP) capability to TomTom Eclipse II

The Navigation/ Audio/Visual unit (Eclipse AVN4430) that came with the RT has a built-in Bluetooth but with no audio streaming capability (A2DP). I bought a Bluetooth bridge (Sprint Anycom A2DP receiver) from ebay for $19, this was several months ago. I was shock to find out that this receiver is now selling for over $90 (Amazon and Ebay).....wow. Anyway, there are other cheaper Bluetooth bridge available out there, just look around. The things that I like about this receiver is it doesn't need an external power and it uses an Ipod connection, which Eclipse has. I do not own an Ipod or Iphone, so the Ipod dongle adapter is useless for me (until this).

*Note to Iphone users: Iphone4 connected via Ipod dongle adapter works really well with the  Eclipse head unit (thanks to Trekker of Sprinter-Forum for the info).  Iphone music playback can be controlled within Eclipse.*

One big warning though, the Sprint Anycom A2DP is not compatible with Eclipse head unit...but...I figure out a way to make it work.


If you look at the picture below, Eclipse senses if an Ipod via cable iPC409 or external audio/video source via RCA is connected and the unit switches between sources accordingly. VTR mode (RCA connection) uses this input.


Here is the fix, by covering pins # 12 and 13 (Ipod receiving and sending line), Eclipse recognizes it as a VTR input not an Ipod. The Ipod connector pins are really small, so you might need to try it several times. I use a small piece of duct tape about 2 or 3 mm's wide to cover the pins. If you have plans of using this Ipod connector other than the Sprint adapter, it's not a good idea to use my "duct tape" approach (as pointed out by a fellow forum member), you have to figure out another way to disable pins 12 and 13 or use some kind of thin plastic sheet to cover it.

Now I can stream music from my Android phone via Bluetooth connection. All you need to do is change Eclipse source to VTR. The BT connection is crystal clear. I can now control the music playing from the back seat while DW is driving. Another great use of "Pandora" while on the road.

Note: If you decided to try a different BT bridge that uses RCA connection, you can make use of the VTR input by unplugging the Ipod cable adapter.
