I had my X993 installed yesterday. I did not have the optional Sat radio or HD radio items installed. One question I have is whether I would need an adapter to install HD radio on it - or if there are enough of the aux connectors already on the back of the unit.
I'm using a 32GB thumb drive with FAT32 and all my music folders organized by artist. With about 19GB of music on there, it seems pretty fast to me. It seems to take less than a second to load folder names for a search, it reacts immediately to folder selections and immediately displays the contents and begins playing very quickly when I push the button.
I am using the Patriot Xporter 32GB drive, which does rank fairly high
in random read access times - it also was fairly inexpensive, at $70 for the 32GB. I strongly suspect random access and fast read times will play heavily into the performance of reading the file system for searches and then playing the files.
If you have access time issues - have you considered the thumb drive performance - as opposed to blaming the HU? While I definitely know far less about how Kenwood has implemented it's USB2.0, it's a very mature format and generally USB2.0 speed issues are due to the device performance more than the USB2.0 connection itself or the controller used.
The display is nice - I like the text options although it is not perfect for me - because I can't find the Artist-only text option - which I would prefer as opposed to the Album/Art option. I have enough room to put them each on their own line - but I can't seem to make it happen. I just got it yesterday - so I will keep working on it some more.
I had to turn the contrast all the way up to be able to read it in daylight. I am not a fan of the glossy front - but I suppose I should have sprung for an LCD touch interface if I thought that was a really big deal. When it's not in direct sunlight - it's really quite brilliant, and I like the color options. They're neat.
I get far better radio reception with this than I did my stock HU. Haven't mentioned it to the installers, so perhaps they did something to help me out.
I really like the audio control options. Being able to adjust speaker distances to provide decent balance in the vehicle is really outstanding. Access is fairly easy for most big items - like sub level and listening position adjustments. I set up the crossovers to my liking already. LOVE having these advanced features!!! SQ is very important to me.
I have not had a chance to adjust the PEQ yet - but I intend to take in a test CD and my SPL meter to do at least some rudimentary EQ - and I am very very excited at being able to do some EQ in my vehicle. I do get some harshness on the high end now, so I think this will help a lot.
I've got a pair of 10" JL subs in a powerwedge with a 300w amp in the trunk - and then some aftermarket Kenwood 6x9s and stock front 6" and tweets in my 2006 Corolla S. The sound seems very good - with nice midbass punch from my 6x9s and decent support on the low end from my subs. I look forward to replacing my stock front 6" and tweets with a good kit - I have my eye on a madisound kit with active crossover.
So far, I am really liking it. I now have ZERO CDs in my car - and every album I own is on my thumb drive. It's really a great feeling to get rid of CDs and not have to deal with skipping or scratching to look forward to. I wish the remote had a search button - because I really prefer to use the remote rather than reach over and use the knobs for finding and playing music. LOVE the remote. Not a huge fan of the push-click controls - it seems sloppy. I'm sure I will get used to it.
Aside from the aux question - is anyone using an iPod with this? Do you just bring the regular iPod USB-charge/sync cord along and plug it in? For road trips I have friends who have iPods and I wondered if that's all you need to do - or if I should be shopping for a USB/iPod adapter cable of some sort.
Thanks and I hope this helps!
