Question about Garmin StreetPilot c550 GPS Receiver

1 Answer

Poor directions For the first couple months, my unit was terrific. I could trust it implicitly to guide me. Lately it has become erratic and I have to check every trip I take. Most of the time it does not provide a 'shortest time'route until I input one or more way points - the last time I did this the time ended up being 30 minutes shorter on a 4 hour route. It also provides a different routing now, for routes traveled a couple months ago. I updated the software, but saw no improvement. Ideas??

Go to setting (the wrench icon) press it, then look for Navigation, then check Route Preference to see if it is set for either fastest time or shortest distance. If you want shortest distance, the upgrade most likely reset it to Fastest Time (default).

Poor starting and erratic tickover


These are great little engines and do not suffer with too many things, first to look at clogged spark arrester in the muffler out let, remove and lean, check the fuel hoses have not become brittle and have cracked and are leaking, failing that check the ht leed where it runs close to the cylinder, is it arcing out? i have replaced a few ignition units, so you can never rule this out.

Few months back i bought kodak c43 easyshare serial no cgxs03913819 from homeshop 18 but now the screen becomes pinkish and unable to take clear snaps please guide


If its only a couple of months old, it should still have a warranty. Certainly a manufacturer's warranty.

Its time to go back to Homeshop18 contact them via their customer care links and ask them for a refund or replacement.

Hi ! My unit do not turn to its right rpm, erratic power.


could be a couple things. UNPLUG tool and remove one handle half and see if it is jammed up with lambswool from the bonnet. It can get under the brushes causing the erratic power. If thoroughly clean the entire motor housing and then remove and check the brushes for wear. Let me know if you need more assistance.

What causes my 2001 grand am gt1 to overheat


Well, before a positive for sure answer can be given, a few questions need to be answered to aid in the diagnosis... 1.)when was your last tune up? 2.) When did your car first start over heating,(ie) did it happen all of a sudden or slowly over time (meaning days, months)? 3.)How many miles does your car have on it? 4.) Have you noticed a small or large puddle under your vehicle lately? 5.) have you had your fluids checked lately? 6.) have you had your smog equipment, 02 sensors, converter, exhaust, etc. checked at its regular interval? All of these questions are important and I probably forgot a few that any normal mechanic would ask but these are the ones that I could trust in to give you a good answer.

Not cleaning well at all. is there some kind of filter i need to clean out?


IF THIS UNIT HAS NOT BEEN CLEANED OUT LATELY DO THIS.
BUY A D/WASHER CLEANING DETERGENT (ANY GROCERY STORE) AND READ INSTRUCTION HOW TO USE PRODUCT.
THIS WILL CLEAN ALL PARTS OF THE D/WASH THAT MAY BE CLOGGED..SOME TIMES THE ARMS ON A D/WASHER WILL BECOME CLOGGED .

ALL DISHWASHERS NEED TO BE CLEAN ONCE EVERY 3 TO 6 MONTHS WITH A CLEANING PRODUCT AS STATED ABOVE..

HAVE A GREAT DAY,LOVE FREDDY

Hello my Palm TX will only show the Media and Install applications on my desktop, even though the hot sync says that it transferred successfully. I have all of the applications checked to be transferred...


your palm may just need a new lcd assembly.
it's not all that unusual the they wear out after some time. have you replace the battery lately??
if not I would start there and if you don;t get better operation look at replacing the lcd as for y it's not transferring apps i would think that could be software related and may a product of you software on your computer.
