This X5 HUD only compatible with universal OBD II and EOBD interface, but incompatible with OBD I or JOBD. Actually, OBD II and EOBD first applied to European and North American manufactured automobiles after 2003, and for Asian manufactured cars, they have even appeared later, since 2007. Besides, some cars, like Hummer and Savana, have special interface, may not compatible with this product, and we suggest A1 or Q7.BR>BR> Features: *Over-speeding alarm: Alerts you if you exceed the speed limit by setting over-speed buzzing alarm. *Multi-color and high definition display: More abundant frames and easy to read. *Adopted nano-technology: Eliminates unwanted reflection to present more definition frames. *Brief projection: The frames are so brief that you can easily grasp very important data, naming speed, some alarms and engine rpm, *Auto and manual brightness adjustment: Automatically adjusts its brightness to provide clearly visible projections both in direct sunlight or at night. *Detect accurate driving information from ECU of your vehicle via OBDII system. Note: If you find out that HUD displays only voltage for 30 seconds and then turn off automatically, this is because the interface isn’t OBD II or EOBD. So we suggest checking twice whether your interface is OBD2/EOBD or not before purchase. For old cars, you should set your start voltage at 12.8V, for your battery is too old to provide 13.2V voltage. The speed this HUD displays is 5km faster than actual speed by factory default. You can fine tune or adjust it to your personal preference. If there is double image, that is because of the double-pane of your windshield, please take advantage of the reflection film present as a gift.
