USB SD AUX MP3 Adaptor für Volvo S40 V40 S60 V70 C70 XC70 S80 with Radios: HU-401, 403, 405, 415, 555, 601, 603, 605, 611, 613, 615, 650, 801, 803, 850, 1205, CR-504

Bought this for my Volvo V70. Very easy to fit and cables are of a high quality with a really good length to allow you plenty of options for various locations. Nice compact size and not obtrusive. Sound quality is first class with no loss of clarity or volume. Switches folders instantly and even works with the random function on the head unit. The Volvo Bus 803 only recognises about 12 music folders but you can store up to 99 songs in each folder so it's not a problem. Very pleased with this unit and would definitely recommend it. No more stuck CDs in the head unit autochanger or waiting for ages for a cd to change.

Not bad at all, a working solution for implementing MP3 from memory card/stick to a factory radio. I wish products like this were available for a wider selection of car audio systems, to avoid all the hassle upgrading slightly older systems to digital audio.

The model for the hu 605 clearly required a positap as do any models with yellow wire & 8 pin aux input...Very disappointed! Should have got a Grom unit. If the simple positap was included it would be relitvely easy to install but until I buy one I can't tell you .Shame on you guys!

Work perfectly, instalation was easy as I use it as aux in only so do not have even connect yellow cable. Sound quality is so much better than through cassette adapter I used before
