: I agree with you, idatalink Maestro Rr is the best in the market and jfyi there is another brand out here called Axxess but Maestro seems to retain most of the factory system features. While Axxess is mainly a steering wheel buttons interface, Maestro does the steering wheel controls, connects to the vehicles ODB2, shows TPMS sensors , extra gauge options and .... so on.
So I contacted an Amazon vendor who kindly called me back and provided the following solution:
1) Pioneer Avic-W8500 NES
2) Maestro ADS-MRR
3)maestro HRN-rr-T01 plug and play T-harness for Toyota
4) PAC USB-TY2 Toyota USB Port retention cable
5) Ai TOYK989 2008-2009 Toyota Highlander dash Kit (mine is 2011 so I am not sure if this an oversight and if I even need it)
All this for $999; it is a little bit above my budget but the vendor who was a real gentleman spent almost an hour on the phone explaining all the details, taking my current configuration information and answering all my questions. And his price is almost $200 below market.
I like the Pioneer 8500 but is still missing some features such as WIFI 3G/4G that most of Chinese aftermarkets HUs have.
So what all you gentlemen think ?
