So i've been looking around for navigation options, and found this on ebay. It seems to have everything I need for installation, and is a very good price. I realize its not top spec, but i figured is anyone here could send some feedback? I can install it myself, but don't really know much/anything about audio etc. Thanks in advance http://www.ebay.com/itm/POWER-ACOUST...ZVy9DI&vxp=mtr

It will be going in my 2002 Lexus GS300 Sportdesign with the normal non-nav/ml pioneer system with the factory speakers

 

save up a little and spend a little more on something with a little more quality. Pioneer/Kenwood are my personal favorites. They have better updates and user interfaces. I'm pretty sure you won't be happy with that unit.

 

another cheaper option would be to get something with blue tooth then use your phone. You can get a better name brand unit and just utilize your smart phone. they also have options where you can use an HDMI cable from the unit to your phone directly

 

Currently have a GROM unit in the car which is great, just figured it would be a nice cheap upgrade. Now that think about it I'll probably sell the car before adding a new head unit
