mars_volta Posted March 29, 2010 Share Posted March 29, 2010 I received my Motorola T605 Bluetooth kit from ebay today. $9.99 + 6 shipping. I mainly bought it for the stereo bluetooth so I can stream from my droid eris. I hooked it up to the garage stereo and I'm impressed so far. I will install it in the car this week and will update. Here is a couple pics for now. http://www.sixthsphere.com/storage2/images/6dm1qtnv4poj1eoi91gz.jpg http://www.sixthsphere.com/storage2/images/6o9sderiz8xibl61raa0.jpg Minus the Bear - Drilling was playing while I took these pics with my droid eris. http://www.sixthsphere.com/storage2/images/imcnrv026c8rozvxefv.jpg Link to comment Share on other sites More sharing options...
utc_pyro Posted March 30, 2010 Share Posted March 30, 2010 How does it sound? I have one sitting in a box waiting for install (I'm putting it in with my '08 radio and line-out mod). Also, if you click "play" on the Droid right after you power the t605 up, will it start playing through the speakers or do you have to switch to audio mode?

mars_volta Posted March 30, 2010 Author Share Posted March 30, 2010 I have to play with it more. I didn't hook up the speaker or mic. I compared it with the straight out from my phone and the t605 was a bit louder. Quality seemed decent. I know I'm losing something using bluetooth, but its so nice without wires. I'm on my second S9 headphones and could not go back. Link to comment Share on other sites More sharing options...
mars_volta Posted March 30, 2010 Author Share Posted March 30, 2010 As soon as my phone connected I could play music. Since you have the tools could you plot the response of the phone/Bluetooth vs wired line in? lossless pink noise file or something? Link to comment Share on other sites More sharing options...
utc_pyro Posted March 30, 2010 Share Posted March 30, 2010 Yeah, I can take a look at it. I can just sync my laptop up to it and do a frequency/time delay sweep on it. Link to comment Share on other sites More sharing options...
mars_volta Posted March 30, 2010 Author Share Posted March 30, 2010 I was thinking about the level difference... I wonder if the 605 has some kind of normalizing? Hopefully not more compression... Link to comment Share on other sites More sharing options...
mars_volta Posted March 31, 2010 Author Share Posted March 31, 2010 Got my Aux-in wired. Sounds great. I need to do the Bluetooth tonight. Hopefully its sounds as good. Link to comment Share on other sites More sharing options...
mars_volta Posted April 2, 2010 Author Share Posted April 2, 2010 I am noticing some artifacts with bass and phasing. Not sure if its the radio and all its messing with my music, my phone or the mp3s encoding...Not terrible but I have a sharp ear and I at least noticed. I haven't noticed this with playing mp3 from cds. I wired my aux in with the FM signal. Could there be some compression, limiting or ?? going on in that path?

utc_pyro Posted April 2, 2010 Share Posted April 2, 2010 Is this through the "aux in" on the motorola, bluetooth, or both? Bluetooth is compressed, but it's unknown what type of compression the phone and T605 will connect up with. It includes mandatory support for the low complexity SBC codec, and could optionally support: MPEG-1 , MPEG-2, MPEG-4, AAC, or ATRAC (thank you Wikipedia). Presuming Motorola cheeped out and went with the lowest common denominator (SBC), your music will be transcoded into essentially MPEG-1 Layer II (mp2) between 128kbs and 384kbs (depending on what the devices decide). On possible fix though: You may be over driving the digital audio path. Start music playing on your phone and lower the bluetooth media volume.

mars_volta Posted April 3, 2010 Author Share Posted April 3, 2010 No bluetooth involved yet. This is straight line in from my phone. Link to comment Share on other sites More sharing options...
mars_volta Posted April 3, 2010 Author Share Posted April 3, 2010 Had a revelation this morning... The 605 has a 1/8" aux in. The bluetooth takes precedence over the line in BUT thats perfect. I can feed the FM signal from the radio into it, and then when I want my music, the bluetooth takes over. Perfect!! No more hard switch! Be back with results..

mars_volta Posted April 3, 2010 Author Share Posted April 3, 2010 Finally got it installed. Works good with my Droid Eris. Sound Quality is good but not perfect. I can hear some transcoding artifacts, and there is some kind of normalization or compression going on. I have to give a good week long road test. In the garage I can hear every little problem. It is very convenient with no wires and it pairs up when I turn on the key. There is a USB socket on it so I wonder if any hacking is possible...

SC GT Posted April 3, 2010 Share Posted April 3, 2010 Does the T605 mute the stereo when using the phone? Also, did you use a harness for the install? Link to comment Share on other sites More sharing options...
mars_volta Posted April 3, 2010 Author Share Posted April 3, 2010 It has the capability to mute, but I don't know if the oem radio does. I did not use a harness. Just tapped the radios power. I did not connect any phone stuff. Link to comment Share on other sites More sharing options...
utc_pyro Posted April 3, 2010 Share Posted April 3, 2010 The 2005-2009 radios have the ability to mute (there is a pin on the i88 conector?), the 2005 and 2006 have a phone audio input that one can use with the T605 to hear the call through the front speakers. The motorla bluetooth kits are the ones that probably work the best with the OEM phone input, the parot kits don't have the correct outputs.

mars_volta Posted April 4, 2010 Author Share Posted April 4, 2010 Today I am a happy camper!! I was listening and was unhappy with the stereo bluetooth artifacts. I discovered that I can plug in my straight line in from the phone but still have bluetooth AVRCP media remote control while its locked and in the cubby! That was my main goal this whole time was to avoid messing with the phone while I'm driving. Sounds great! http://www.sixthsphere.com/storage2/images/ztuq8u4ek6vzx2kxgfc3.jpg Link to comment Share on other sites More sharing options...
SC GT Posted April 4, 2010 Share Posted April 4, 2010 Did you connect the T605 to an "aux in" like Jazzy's or Leptronics? Link to comment Share on other sites More sharing options...
mars_volta Posted April 5, 2010 Author Share Posted April 5, 2010 Kind of. I just hacked the FM signal traces. I brought the FM and new line in out to a DPDT switch and fed the other side from the t605. Zero noise. I saw no need to use an internal relay and all that. Use the proper wire and it should be fine. Here is the original thread. http://legacygt.com/forums/showthread.php/my-2005-legacy-ipod-input-21047.html?t=21047 Link to comment Share on other sites More sharing options...
mars_volta Posted April 11, 2010 Author Share Posted April 11, 2010 Couple new pics: Installed my FM/Aux switch and a power switch for the Bluetooth. In case I need to reset it, I don't need to shut off the car. Anybody have an extra ashtray assembly? http://www.sixthsphere.com/storage2/images/ipotodzy6hgx4rgr6je.jpg http://www.sixthsphere.com/storage2/images/wwe8ir6qxwdl8lzpc64.jpg Link to comment Share on other sites More sharing options...
Masshole Posted April 12, 2010 Share Posted April 12, 2010 You've inspired me. I ordered one on eBay and am waiting for it to come in. Looks like the phone portion can wire into the factory 05 harness locations for +/- phone and signal. Link to comment Share on other sites More sharing options...
mars_volta Posted April 12, 2010 Author Share Posted April 12, 2010 hopefully you didnt pay more than $15. Its a nice unit, but the stereo bluetooth stream quality is lacking. There is some research being done to find a better setup. Link to comment Share on other sites More sharing options...

There is some research being done to find a better setup. The setup I probably would have upgraded to (if I hadn't found a Spec B radio with aux input) is the Parrot MKi9000/9100. With the quick connect harness, it should be plug and play, and plays music through the Parrot box via bluetooth, Ipod adpater, USB or 3.5 mm aux jack. A company from Israel is selling refurbs on ebay for close to $100 shipped. Sounds like a really good aux-in/Ipod alternative for people with the 05-06 non-aux head units.

There is some research being done to find a better setup. I've never had a great experience with A2DP, so I wasn't planning on using the music portion. I'm more interested in doing away with my headset and having a decent hardwired speakerphone Link to comment Share on other sites More sharing options...
