Got my Stiletto about a month ago and love it. Have not experienced any overheating although it does get pretty warm. I have trouble with the car kit as it does not always work and I can't figure out why. Trying to get through to Sirius tech support teaches one a lesson in patience as it takes forever to get through if at all. The earphones with the antenna are extremely uncomfortable, I mean what were they thinking! I am using the unit in the boombox and I found the antenna that comes with the unit is not that effective so I ordered the bigger antenna but have not hooked that up yet. I do like being able to take the unit out of my vehicle and then use it inside in the boombox, which has a very good sound.

I have had this for 7 weeks and the reception is terrible. The unit gets so overheated so quickly, it will shut itself off and you have to hold it to the a/c vent in the car to cool it down. I take it inside me everywhere I go and it still won't come on everytime I put it in the car kit. The Stiletto 10 comes with a carrying case (a thin nylon bag), but the more expensive Stiletto 100 doesn't have that luxury. I have yet to mount it because the vent mount only works on certain cars, and the other mount is a sticky one and I am scared it will not hold. I previously had a Sportster Replay and this Stiletto doesn't have have some of my favorite features from the Sportster. There is no Seek function, although you can just record the song and play at anytime. I have used this outside without a boombox or car kit and the reception from my front and back yard was horrible, so I had to listen to the recorded songs. If you use the big headphones, then you might get a better signal, but I couldn't stand those things in my ears for more than 10 seconds. Good luck, I might have gotten a lemon. I am very disappointed.

Good and bad things to say about this unit. First the good: Portable feature is nice, seems as maybe Sirius has been working on the signal. I notice it works best with a full charge. WiFi is awesome! Although you do not get access to all the channels. The ability to record favorite tunes and programing is nice. Allows to to store lots of music. Display is nice and clear. Now the bad: Unit does shutdown when it overheats. Reception on a FM station is poor. No artist alert feature. All in all it's a pretty cool unit. I would highly recommend the service plan on it though. I'm on my second unit. The select wheel went bad on the first one I had.

I have had my SIRIUS Stiletto 100 for about 4 months now (replaced the Sportster IR) and I am enjoying it thoroughly. Aside from the usual satellite radio channels, the Stiletto 100 offers up recording of songs (press the heart button). It then gets saved in your library. In addition, you can download songs/podcasts from your PC to the Stiletto. Coupled with the car kit, it gives you direct number access to the various stations, it DOES NOT have this w/o the car kit. The interface is very easy to use as you perform clockwise and counter-clockwise motions to navigate the selections. You also have back and home buttons to make things easier. If you are looking for a portable SIRIUS radio you cannot go wrong with the Stiletto 100.

This is a great product, the recordability is wonderful. Battery life has a little more to be desired. All in all though, I highly recommend this product to anyone who wants to take their sirius on the go.
