I have a Blaupunkt San Francisco HU. I paid about $300 dollars for it about a year and a half ago.
It has a lot of feature, but i have been having problems with it.
If i try to adjust the volume down a lot of times it will blast the volume up and i have to fight with the knob to go down; i'll be trying to make volume go down and it will start fluxuating. The cd's skip easily, the radio stations sometimes jump to another station when listening for no apparant reason or just goes to mute, sometimes it switches from cd mode to radio, sometimes one cd track will just skip to the next song, sometimes it says the id card is invalid and i have to take out and re-insert.
Seems to be a pain in the a**.
Lot of features yes, but reliable, no.
