Alphard ATH20W Tesla style Head Unit

Recommended Posts

Thanks for your reply. I attach my mobile hotspot to this after market headset and location is set to my home town. Satnav and other things that should require location work fine so 8m at a loss here

if it anything like other tablets/phones (which this is basically) the compass needs calibrating by moving and rotating the head unit in a figure of 8 - practically impossible of course.

I noticed that Google maps wasn't working correctly and found that a cable at the back was in the wrong hole. I put this in the right plug and both maps and the compass works nicely now. Thanks for everyone's help.
