A good value.

Seems to be a good receiver. Many good features. I need better speakers to really reap the total benefits.

Alright...

This product is alright. It doesn't automatically shut off when my car turns off which can at times be a nuisance. I was also under the impression that I could hook my iPod up to this device with a USB chord but I have found that I need an auxiliary chord instead. These are just little problems that add up but other than those it is great

This product should never have left the design phase. Do not buy

I bought 4 of these from Sonic Electronix, installed them in four different cars, and all four of them have the same problems:
1. the USB port doesn't charge devices like ipods or phones.
2. tried playing songs from a USB drive and nothing happens.
3. the radio forgets the stations you've stored in memory (or forgets some of them and moves the others over to different buttons).
4. the "PI Seek" feature (my family calls it the "PI SUCK" feature) comes on in the middle of a song or right at the climax of a story on the radio and it takes like 2 minutes for it to find the exact same station it started on....and there's no way to disable the feature.
5. On one of the units the aux out jack broke with very little strain on it. On close examination, the faceplates are very cheap and delicate. The jack is plastic and broke apart inside the faceplate.

One last thing: the user manual that comes with it is not very clear. I think a second grader wrote it.
I feel like an idiot for being suckered into buying these. I guess if you only listen to CDs then it might be worth it.
