It works but...


Overall, I love this unit, but hate the lackluster customer support from Cobra. Several emails about this product, posted via their own web site, have gone ignored for months now. Based on the quality of the unit itself I'd rate it 4 eggs, but the...

Excellent display size, and the auto-brightness feature is very good. Takes a little while to learn, and the on-board help functions work well for most things. Accuracy seems to be excellent at +/- 15-20 feet. Traffic info reception also works very...

The POI database needs updating, but there seem to be no updates beyond August of 2006. Has an annoying tendency to want to take any road that goes to the right, then rejoin the main road. (It keeps wanting me to drive through the entrance driveway...

Good Value for a Basic GPS


My girlfriend and I recent took a trip from Colorado to California; without GPS the task of navigating and driving in portions of California would have been next to impossible. If you want a good value GPS with traffic updates but where cutting-edge...

Large, bright screen. Navigation and directions given are good to excellent. Six million points of interest

Some of the points of interest are out of date (last firmware update was in 2006). Sometimes the unit is slow to calculate directions, especially from a standstill--it likes to be moving when calculating. Traffic data works fairly well and will...

Don't buy This


I bought this because of the Cobra name - I wanted a good functioning GPS that would just work - This is not it. Read the warranty - Newegg will NOT take it back.

Big Screen - Easy to understand / View / and Work

Basic purpose of GPS - THE MAPS - they are out-of-date and wrong. Major streets are mis-labeled. Map shows turns where roads do not exist (and I've lived here for 40 years). POI also out of date. No internal battery (not portable). Cobra is...

Excellent GPS


Fits perfectly in center dash opening of BMW X3 - without any accessories.

Large bright screen, traffic information, two routes to choose - the fastest and the shortest, options to avoid highways or toll-roads

Bulky, no built-in battery. On few occasions it tried to convince me to leave straight route and accomplish right turn, U-turn, right turn on intersection. Other that that - no complaints
