Summary: I purchased the MNA-2300EXT external GPS antenna for this model from Cobra along with the cable adapter that converts the four contact mini plug to the RJ11 telephone type connector used on the antenna. The GPSM-5000 will not recognize the external antenna.
Summary: I miss not getting to use this GPS, due to not being able to get new maps since the Cobra no longer provides them. It was the best GPS of those that I have since purchased, like Magellan, Garmin and TomTom.
Summary: I had this unit 10 months or more and had the software updated to 2.4.0 if you dont have this it may do wierd things. The bluetooth is not very good when i used it the other person could hardly hear me so i gave it up.
Summary: I don't know where to start... I purchased this unit for the large screen and red light camera ad a couple other features. The screen is large but the area that the map is in does not cover the whole screen so you end up with less map area than most 3.5inch gps's. That was my initial complaint...
Summary: This is certainly the worst product I have used in recent memory. It was given to me by my brother, who bought it in hopes of upgrading his aging TomTom, but found that the Cobra was pretty much useless, despite its advertised improvements (Voice to Text, Bluetooth, etc.).
Summary: April 15, 2009 Ive never written a review ever. This purchase left me with such a bad feeling that I just had to write about it. I spent hours reading all the reviews about this product. Reviewers talked about the red-light and speed camera features.
