Preamble: my car (2002 Alfa Romeo 147) has a pretty cool BOSE audio system. The problem is that the radio itself is outdated, and can only read regular CDs. About any MP3, and especially flash drives or bluetooth even out of the question. Theoretically, you can order a more modern radio from an authorized Alpha dealer, but it will obviously cost more than a car. Since the device is special and only for this model, replacement with something newer from the nearest Mediamarkt is also impossible, because get a frank collective farm.
About a year ago, was bought such FM modulatorbut the sound quality was so-so and after a hot summer it lost its presentation
It was decided to purchase the device in question. It is a CD changer emulator and connects to the AUX input.
The product was ordered on September 24, shipped on the 26th by Swiss Post (suddenly) and reached October 17th.
Arrived in standard packaging with a little bubble
The box is a little dented, but the contents are not affected.
Inside the device itself, instructions in English and three corresponding cables - USB, signal and two-way 3.5 mm.
The signal cable is used to connect tocar radio and is distinguished by one of the connectors. In this case, this is a connector for Blaupunkt models, which are installed in a number of Alfa Romeo and Fiat models, but there are options for "Japanese", "French" and VAG - look for the YATOUR keyword.
Cable length approximately 70 cm, i.e. problems with installing the device should not be.
The case is made quite durable, from thick plastic with a metal middle part. It did not work out, so there will be no dismemberment.
Installation is theoretically simple, but I had tosweat. The radio tape recorder is removed with the help of standard U-shaped pullers. On the one hand, the lock was unlocked, but on the other did not want to. Had to retrieve using physical force.
On the rear side of the radio, connectors were found, one of which was exactly like on the cable.
K.O. suggested that you need to go there. But first, it is better to turn off the power.
Three color connectors are pulled out together and secured to each other with a dovetail with a latch. Just remove the blue connector and stick a cable instead.
I previously planned to put the adapter inbox for little things - in the first photo he is under the radio on the left, but he did not fit there. I had to amputate the stand under the glass, which is on the right - anyway, I do not need it. It turned out like this.
Everything started up and was recognized immediately, but there are a number of features.
1. Albums should be located in directories with the names "CD_01" and so on. Other names are ignored.
2. Up to 99 albums and up to 99 tracks in the album are supported, but no more than 999 in total (arithmetic is somewhat strange, but it will do).
3. Tracks located in the root directory are not visible.
4. It was checked with cards and flash drives up to 8 GB, everything works (but are such healthy cards necessary?).
5. Management is similar to a conventional CD changer and depends on the specific type of radio.
6. MP3 was played with a frequency of 44100 Hz and a bitrate of 192-256. I did not notice the difference between different bitrates, but compared to the old FM-modulator, the quality is significantly better, there are tops and bottoms.
7. The volume level is lower than when playing from a CD. Perhaps this depends on the overall signal level in MP3 files, but I'm not sure: playing music from different sources gave an identical result.
8. If the radio is turned off, then the continuation of playback sometimes starts from the same place, and sometimes from the next track (in the council, while this is the only jamb seen).
So far, it has not been possible to verify how the device behaves in the heat, for lack of such.
There is an additional connector 3.5 mm to connect an MP3 player or phone to play music from there. Works. but it’s rather inconvenient to use, and again you must follow the directory naming rules.
Summary: for owners of new cars with overly branded radio tape recorders, this is a good solution that allows them to be upgraded without much loss for the interior.
