Updated November 10th, 2008 TeleNav caught everyone by surprise on Friday when they launched the TeleNav Shotgun connected PND. This is unexpected because it was announced last week that the Dash Express, the connected PND poster child, was being terminated.
Contrary to Dash and deCarta (powers BestBuy's Insignia), TeleNav have a lot of "consumer GPS" experience thanks to their Mobile GPS software available since 2005, assuming they're using the same navigation engine. The map rendering doesn't look "great" though compared to Garmin's or TomTom's especially that 2D vehicle arrow...Let's wish them good luck, but the pricing might be a problem, $299 upfront is reasonable but $12/month or $130/year for the service paln not so much, they'll really have to offer much better traffic than Garmin's RDS or MSN to pull it off. You can use this topic of the "GPS and Mobile News" forums to discuss.
Updated February 1st, 2006 - After Garmin and Telenav's solutions that some visitors tested side by side (see below), here's another competitor on this "off-board" market, Verizon's VZ Navigator. Monthly pricing is similar at $10 per month but they have added a one day $3 option that could come in handy on the occasional trip even for regular GPS users in case their "on-board" setup lets them down.....
Updated 09/16/2005 - For those looking at these new phone based navigation options, you can take a look at the comprehensive feedback offered by robogps in this thread as he tries out Garmin Mobile and TeleNav to see which solution bests fits his needs.... and if he can use either instead of a dedicated GPS solution like the SP2720. Highly recommended read and as always "sharing the information" on GpsPasSion!
Posted 09/05 While it seems that for the most part, the USA have not had access to Smartphone based GPS assisted navigation now quite popular in Europe with TomTom Mobile or Mobile Europe by Route 66, they are clearly taking the lead in phone based GPS navigation with offerings by Sprint (Nextel)with Telenav based solutions and now Garmin Mobile based solutions... The navigation platforms are the Motorola iSeries GPS enabled phones (SiRFII with SiRFLoc AGPS) and the promising Blackberry 7520 (SiRFII with SiRFLoc AGPS). Unlike the HP 6515 that relies on "user plane" AGPS (the user downloads the AGPS data via GPRS), SiRFLoc relies on "control plane" AGPS handled at the network level (more details on AGPS here).
