Man... this is getting on my nerves, don't really know what to do. My order of a F900BT has been delayed until 30/06, at least. Besides the apparent incapability of delivering, the long boot time bothers me a lot. I keep getting in and out of the car all day long, and if everytime I have to wait for 1.5 min, I'll soon get aggravated. Also, I'm a little wary of the idea that new firmware will reduce those boot times... If a computer takes a long time to do soemthing, that's usually because it cannot cope with the load.
Reading all this, I'm clearly considering other options, all of them more expensive, but apparently a surer bet:
Kenwood 8220BT, ugly interface but apparently quite good at all the rest;
Clarion MAX983HD, only for 08/2008. Very, very, nice interface, based on the MAX973HD. Clarion has also made some of the closer to true hifi HU I know of;
Alpine IVA-W502R + NVE-099 + PXA-H100 + KTX-100 + KCE-300BT + KCE-422i. The number of components is laughable and would complicate installation, but it does offer so much more than any of the others. Further, lots of boxes usually means decentralisation. For example, the separate nav unit of this thing has its own 64bit processor. I don't think it gets in the way of the boot process of the HU.
I have an old Blaupunkt RGN-08 attached to an old Blaupunkt RDM 127 New York in my wife's A4 and you can do whatever you want with the radio until the nav unit boots (20 seconds at most, anyway), and imediately when you turn the key.
Also my also old factory PCM1 system in my car boots to radio instantly, starts playing a cd in the changer in about 5 seconds after and boots to nav in about 15 seconds.
If I then jump to a thing that boots after 1.5 minutes, that's a major downgrade....
Oh, well, now what to do?
Your thoughts will be appreciated....
