I've read a lot of conflicting information on this... do any actually exist? Some say that CNDV-80MT contains one but 90T does not. I have neither... does this mean I need to purchase both to get the firmware upgrade and the newer maps? Thanks, Michael

I noticed after loading a background onto my D3 that it looked badly posterized, suggesting that the D3 was down-sampling the color depth of the picture. Does anyone know how many colors the D3's screen is actually capable of displaying so that I can do this in advance to improve the results? Thanks, Mike

The D3 doesn't use reverse or speed wires to lock out functionality while the car is in motion--so it has nothing to do with the bypass at all. In fact, it only uses the parking brake wire, which can be grounded if the other modification is made to the pin on the RCA harness. You SHOULD definitely hook up both the reverse and speed wires. Without the speed wire in particular, the D3 is unable to accurately determine your position. It will work without them, but not as well.

I recently purchased a D3 from CarTronixPlus. They claim to have this accessory for $12.00 a "Install Kit" or something like that supposedly has the wiring harness "for your vehicle." I don't see a way of actually specifying my vehicle. Does anyone know what this is? Or, failing that, does anyone know where I can get the appropriate wiring harnesses? (I drive an '07 scion tc). Thanks, Mike
