## Description

This A8 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. Specification: Type: Head up display A8 Display type: Digital Car Make: With On-Board Diagnostic OBDII interface Product Size: (4.92 x 2.95 x 0.59)&quot; / (12.5 x 7.5 x 1.5)cm (L x W x H) Screen Size: 5.5 inch Environment: ~40c+80c atmospheric pressure 86-106kpa Alarm sound level: >>=30db Working voltage: DC9-16V Working current: 40mA Sleeping current: 15mA Compass precision: &#xB1;1&#xB0; Speed range: 0-400KM Note: If you find out that HUD displays only voltage for 30 seconds and then turn off automatically, this is because the interface isn&#x2019;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.

Awesome! I love this speedometer. You can adjust the speed if it's not reading right on your actual speedometer. It has many features from reading the battery volt to adjusting the RPM if it's not reading right on your actual RPM gauge.
