What does the Aux battery work for ? (SBC only? )
Can I tap the 12V power from this baterry for a rader detector ? (It will be installed under the hood) or I should wire from the main baterry ?

In the hopes that noone takes this set of red warning errors lightly, please get it to the dealer ASAP. If the batteries lose power, and you have problems related to the BCU malfunctioning, you will have a significant chance of losing your brakes entirely while driving. It happened to me. That is not an SBC related issue as some may automatically think, but an issue with the electronics that MB set up to support backup power to the engine, and consumers in vehicle..Trust me, you don't want to lose your brakes, 7G transmission, power steering etc. while driving due to this error.

The $125 was for the battery -- I installed it myself. The reason your plane battery is $30 is because it has a Beechcraft part number on it instead of an MB part number!!!
I choose Beechcraft for an example because I would expect someone who owns a Corvette & an E500 to fly a Bonanza V-tail.
