MP3 car stereo wannabe

I got this thing for Christmas and I decided to install it the other day. At first it started nice and it looked great (but a little bit dorky with all that UV-meter wanna be display).
The remote worked for about 1 day, and the next day it completely stopped working. I have tried resets, pushing all the buttons, holding down buttons, several at a time, to no avail.
Yesterday I loaded a FAT formatted 1GB SD card with some mp3s to play in the stereo, to check that feature. The mp3s play good, display is alright, but when you turn the engine off it will not remember where was it in the last mp3 (no bookmark capability). This is pretty fundamental, as I like to listen to podcasts from time to time, especially when I am travelling.
The second thing about mp3s is the random mode does not seem to stick after a power cycling the unit. This is also pretty bad, as listening to the songs always in the same order is not funny after a while.
All in all this little unit promises a lot but shows up pretty empty when it comes to some fundamental features. Unless I can get some help with some of the items here I will return it to the store.
