2006 Navigation and the AM Radio Problem

I recall reading on this forum somewhere that a number of people have had problems with their voice activation commands. In particular saying "AM Radio". The navigation system will repeat the statement but will not chage the radio to am. I took my 2006 (newer graphics) in to Toyota to see about getting this fixed. The first thing they did was change out the radio cd combination. They also failed to give us back our six cds. They claim that Toytoa will send the cds back to the dealer. However two months have gone by. Well back to the story. They fix did not fix the problem. They then ordered a radio ecu. We waited for about three weeks and after repeated calls found out that someone at Toyota decided that it was a know issue and that a new DVD disc would fix the problem. So they were on back order so another couple of weeks. They finally got it in and we showed up. The DVD disc would not work as the system could not read it. So they decided that the original ECU was the correct problem.

Questions:

1. Does this sound correct?
2. I purchased one of the lock picks to allow us to use the navigation while driving. If they get the new disc to work will that unit still allow us to navigate while driving?

By the way I tried unplugging the wires from the navigation unit and then placed the new DVD unit in. It still could not read it. It reads the one that came with the car without a problem.

The DVD that originally came with the car is labled North America U40 D DVD ROM ver 05.1 2004 Navteq
The new DVD is labled North America U01 DVD ROM ver 06.1 2005 Navteq

Help!!

I appreciate the reply, however that does not address the questions. Does anyone know if the two discs that I highlighted are compatible? Also in getting the am issue resolved did that negate the benefit of using the base lock pick
Thanks,

Isnit odd that I could not get the newer disc to load. I tried diconnecting the power to force a boot. But nothing would get the system to read the disc. So even though I have the more current system a new disc is not guaranteed to work.
