I purchased my head unit last year from a reputable ebay store and installed it in a 2004 Toyota Sienna XLE mini van. I am an experienced car stereo installer with more than 25 years in business. I previously had a Clarion touch screen unit with NAV in this vehicle, but it was extremely slow to respond and I wanted something that would work as quickly as my Samsung tablet. After searching the internet and much research on youtube of end-users of this head-unit, I decided to purchase and install the TH8681GA unit. Initially I was very enthused about the functionality and response time of the product. I even encouraged my brother-in-law to purchase one for his Subaru. After only 3 months of use, the screen began to fade out, giving me a washed out look with a burned in radio screen permanently etched in the view at certain angles. The Basarsoft-IGO NAV system is very good, but it does not hold the memory of my selections for setup; language etc. The other memory functions in the radio remain set, so I know that the problem is not in the constant power 12V supply wire. Now the radio tuner intermittently decides to scan forward until it comes back to the station that I was listening to. Is there anything that can be done with this radio? I was hoping for durability with this product and at the price, a value that would allow me to install it for my customers. Disappointing:(
