PC Miler PCM430 4.3-Inch Portable GPS Truck Navigator

I got this in August from Dieselboss and it already had the new maps on it. It definitely made a huge difference once I set up my truck and road profile properly. It came with the settings on "default" which drove me like a car until I read their quick-start guide and saved a profile that matched my truck's height, weight, length properly. It also has a further setting for favoring the larger roads (interstates) and telling it to NOT use local and smaller roads. I agree with other reviews about the speaker because once you have all of your truck noise it is difficult to hear what it is saying. I bought an FM transmitter and plugged it into the headphone jack and now it's nice and loud out of my stereo speakers. I don't need the voice out on open, long stretches of highway anyway and only turn on the FM transmitter to hear it when I get close to my destination. The new maps also seem to have the points of interest (truck stops, weigh stations, WalMarts, etc) very accurate... more >>

I bought this GPS and returned it within 24 hours.Can not hear the speaker inside a truck. Every road shows as a restricted truck route. Hard to view in the daylight. No truckstops are listed in POI's. Tried to send me off on a county road. A good auto GPS is a better buy. PC Miller in any form is not a good buy... more >>

This GPS is years out of date. Major roads are missing, Most addresses are missing. I have a cheap GPS also that is twice as good as this one. I even emailed the Support center and ask for an update. They want $99 for and update. I think I will just spend the $99 for a better GPS and take a loss on the money I spent on this junk. THe GPS is great except for the maps. What good is a gps without the maps... more >>
