Up for sale is a factory rear view mirror from a E46 3 series that has a Valentine 1 concealed display installed inside the mirror. The mirror will work in most BMW's - the only car I know it won't work in is a E46 M3 that has the factory SOS mirror. This mirror was installed in a E39 M5 before it was sold.
Please note the factory auto dimming glass has been replaced with a custom two way mirror that hides the display unless the unit is turned on. Auto dimming will no longer function. If you're not familiar with the V1 Concealed Display it does not include the V1 Radar Detector. This is a remote display that runs off the main V1 unit.
These normally sell for $499 plus the cost of the V1 concealed display ($39)
First $299 (plus shipping) takes it.
