The unit becomes pretty much unresponsive to the remote control when I am driving in my car with the top down during the day

The new unit works OK, accept now my original battery will not hold a charge and I have to by a new one.

Hopefully these are just bad units which can happen in complex pieces of electronics.

I'm rating this 3 stars, just because, in reality, if I ever get one that lasts, it is a great portable unit with recording capabilities.

** I replaced the bad unit with a new one as my Motorcycle was wired and setup for this model

As such I would strongly recommend a portable XM unit to anyone who travels frequently and likes hearing the latest music w/o buying individual songs

After doing some research, I found that I was a victim of having one of the crappy units that gets stuck in this "powering up" mode, and never goes any further

My unit died 11 months after I purchased it.

After some weirdness that started about 3 or 4 days ago (freezing, shutting down, hanging etc - mostly while listening to MP3's on my SDHC class 4 8GB card), my unit began to hang regularly every few songs.

This is a good unit, but I have several issues with it

I can promise you a full featured unit that is cheap in build and ready for the junk drawer

I even bought another like new Pioneer XMP3 off ebay in case my original unit ever quits working

My unit worked great... right up until it quit working and gave me the permeant 'Powering up' screen, until the battery dies

(maybe i got a bad unit?)

The unit I purchased on 12/15/08 died a few days ago

The unit generally works for me

When playing MP3's, sometimes, not every day for sure, the unit freezes.

The unit works quite well in my car with a cassette player adapter playing the XM broadcast from the headphone jack.

Thus, I got a new unit from Best Buy at no extra cost, and it works very well in both the car docking and the home docking.

1st unit failed after 2 months, second unit failed after 5 months

I only used the radio once as a portable unit

The only down side (when you are using it outside as a portable unit)is if the signal is weak in your area you may have to use the recorded content

So, I basically purchased an expensive home unit at that point

The MyFi unit was almost useless without an external antenna - except in my office where there is a strong terrestrial signal.

This unit is easy to use, and I also like the ability to store my own MP3's

This unit is great (as long as it is working).

My unit appeared to flake out and the screen would periodically flash a blank screen for a millisecond.

I bought this unit in October and loved it, went everywhere with me then a few weeks ago (hooked to the stereo) it just quit... when I went over to check it

Beware this device!It has a well established software issue that will completely disable the unit

was gracious enough to exchange my defective unit 6 months into the 1 year warranty because Pioneer support is extremely poor and unreasonable

I'm now using my 2nd defective unit

The first unit that XM sent me worked for 1 week, then the MP3 function stopped working

Overall, a good unit, my favorite of all the xm receivers that I've had, but it could be better

That is why we have rated the Pioneer brand awesome because the Pioneer brand is a great unit

Overall, nice unit.

This unit is a huge improvement in almost every way.

As mentioned in my heading, this is my fifth home/ portable satellite unit, replacing an Inno I have had for nearly 3 years.

These units can die and transform into expensive paperweights without any warning.

It's a great unit.. but reliability is TERRIBLE.

Unfortunately, the heat destroyed the unit

unit is reasonably good, except for battery life, my xmp3 is 10 months old and I'm on my 3rd battery, each one after 3 months will only give me 30 minutes of service, at 29.99plus shipping it a joke.....

There needs to be some kind of protective shell that protects the unit AND lets you use the player in the cradle

11/15/2009 - I've seen a lot of people talk about faulty units.

I don't like the fact that the unit is so expensive

I have four XM radios in use and decided to replace a MyFi portable unit with the XMP3 when the charging port became a little finicky.
