I have had my 718B since August and loved everything about it except having to hit the engine/start/stop button every time I started the engine. Today I installed the Memory Module from T-Design and now both the sport and engine start/stop buttons stay in the last position selected when you restart the car. I love it. If you buy the module, it is easy to install yourself. The only problem I had was taking off the trim around the console. There are 10 push button clips and it was very hard to pop them up. There is no way you can just lift up on the back and they will pop out. If you do that I am sure you will break the trim. After getting the two back ones open I used a screwdriver to pry them up one at a time. The rest came apart easy and all reinstalled very easy. They have a very nice video on their site showing how to install the module. A very nice aftermarket product.
