Did you get this sorted out? We have the same vehicle. I just ordered the Continental. Thanks!Hello. I realize this post is old, but as usual this forum is one of the very few places for any information at all on a multitude of topics concerning our cars... not always accurate, but something (even an email to Becker regarding radios was utterly useless). What year r129 did you install the TR7412UB-OR into? My 92 r129 has the receiver in the trunk and the amp under the passenger seat. Crutchfield sent the wrong wiring harness twice, telling me I can use any aftermarket deck with their harness (Crutchfield has actually never provided correct information even once about any MB I've owned). After giving up on their solution, and selling the Alpine I had bought for the car I decided to send the current deck to Becker to have an Aux In added. After my email exchange with them I don't think I'd trust them with anything. I'd love to pick up an TR7412UB-OR if it will give me modern audio options. Cheers.
correct. loudness is to try to make the frequency response match the fletcher-munson curves for hearing. (equal loudness over a wide frequency range) the ear is not a linear device, suprise, and at low volumes low frequencies aren't percieved to be as loud as higher frequencies.No, loudness on/off is not automatic vol control
See RED above... Hope this helps.OK, just read through all 25 pages of this thread...I have some questions/confirmations based on what I read.
This is for a 97 R129 with the stock Bose set-up;
1) It appears that the CD changer in the trunk does not work with this new unit. I did not read any comments that implied that was not the case. Is this true for all of the the Conti models? Yes, to the best of my knowledge
2) It appears that folks are happy with the voice reception of the Mic in the faceplate and therefore have not been connecting the MB factory Mic to the unit. Has anyone had better experience with the factory Mic and think it is better to use it? Don't know...
3) You need to reverse the A4 and A7 adapter cables but other than that change it should be plug and play. Exactly, If i recall numbers correctly.
4) Bluetooth connection seems to work well and playing media via bluetooth also seems to work well. Generally I did not see any bluetooth complaints.
5) playing MP3s via the USB input I gather works OK but navigation is difficult. Has anyone tried connecting an iPod to the Aux input on the front faceplate? If so, is the sound quality OK? Did you use 30 PIN to Aux adapter OR us headphone jack to Aux adapter? I assume if you do this you still navigate songs via the iPod interface? I tried USB to IPOD... Got Bupkis!
6) I did not see too many who looked like the purchased the CD unit, but for any that did have you burned MP3s to CD and played them that way? How was the interface through the playlists, etc? Better or worse than USB? No CD for me
7) When using Bluetooth for phone calls, if you are connected to the unit can you just use your phone to initiate phone calls so you don't have to mess with the clunky interface? I assume once the call is initiated it will just audio via the bluetooth automatically. Can initiate by phone. Apple SIRI works good
8) Regardless of model, for the R129 cars we should order a 12V unit not 24V, correct? Correct
9) I never saw a response to the question if anyone has been able to use a USB drive larger than that 8GB max size that they specify. Haven't tried, so no idea
Thanks again to all who have shared their experiences. This information has been super helpful.
I agree with all of Ears answers. I have uses an iPod in the aux port 1/8" to 1/8" cable works well, and navigate thru the iPod. Another new bonus for me anyway, is that my new subscription for Sirius satellite radio added streaming of all channels for $5.00 per month. I have it in my modern cars, and now can have it in my older cars. I never spent money better than this radio upgrade.
@jasonformanI did not make it work. I brought it to two different stereo installation places and it would have been 800-900 to put in.
I found an AMAZING option though. There is a place called Creative Car Audio Shop in Southern CA https://creativecaraudioshop.com/
And they were able to install a bluetooth unit into my receiver. Since it's quite far back, I need to keep my phone closer to the trunk. It's a small shop and very cool fella running it, I forgot his name unfortunately. I can find if anyone wants. He wasn't completely happy that the bluetooth didn't reach all the way to the front, so he's offered to tinker. I love people like that... I would have actually been happy with the solution even though it wasn't perfect, but he really cares to get it right.
This cost me $200 bucks and I get to keep my original stereo.
Now I just need to return my Continental.
Thanks for all the help! I can give anyone more info on the above mentioned car shop if they want.
