No excuses for getting lost with HTC P3600 ROM Upgrade :-)

As mentioned in my previous post on PDA and phone convergence, the HTC P3600 that I purchased has in its circuit board a GPS receiver, but it was not enabled in my version of the phone. During the past weeks I had been scouring the Web for signs of an official ROM update that might include this. The Asian version (for the Dopod equivalent) had been released in February, but the European version was slow to emerge until news spread via sites like XDA Developers of the official WorldWide English (WWE) release becoming available in a few countries such as Belgium, Sweden and then Italy.

So where was the ROM for UK users? It was a bit odd - I had read of people's queries to their HTC sellers with generally noncommittal responses. Wanting some clarification of the situation, on Tuesday (3rd) I got in touch with Smartphones Direct, the company that had sold me my phone, using their Java-based online chat facility. I asked about the availability of the HTC Rom update to include GPS and at that time was informed that it wasn't available and that even an official ROM download would invalidate the warranty, but there was the possibility of the company installing it for me for a fee.

Disappointed, I was wondering what to do. However, I kept dipping into online fora and the next day I was encouraged by a thread on the Expansys site. It was great news - an official ROM to download from HTC Europe's site. I proceeded to download and was expecting to install straightaway, but I hit a snag - I had left the sync cable in the office and the next day I was on leave and due to be travelling in the afternoon! Never mind. This morning I popped into the office, collected the cable en route to a bit of shopping, then raced back home and carried out the upgrade and it was fine.

Naturally, I was keen to try out the GPS. I see they have since added TomTom Navigator as a freebie, but I was travelling by train this afternoon, so instead I installed VisualGSPCE. Having never used GPS before, I don't know what to expect, but I find this a very nice piece of software that is easy to use and provides very clear details of your co-ordinates (longitude and latitude are very accurate, but altitude seems to fluctuate quite a bit more) plus your velocity. It also shows some stats about the satellites - how many around, how many are being used (have strong enough signal). After installation, I found I needed to do a restart of the PDA and initially it gave an error because by default it was expecting communications to be on COM1; changing (via the app) to COM9 enables it to work. From then on it's a doddle!

My colleague Matthew had alerted me to an article in The Register in which they had tested the GPS in the Orange SPV M700 (rebadged HTC P3600) and they had found it drained the battery as much as talk time, i.e. to about 4.5 hours. One of my other colleagues has the Orange phone and had already tried the GPS; I haven't got round to asking him about battery life, but I think his ROM is dated January and since then I've read very positive remarks about improvements in this area in later ROMs (the HTC WWE one is from March).

So I ran a test. Just before my train arrived I switched on the phone, got a lock (within a minute) and left it on for the duration of the journey. VisualGPSce has a logging facility, which I remembered to switch on just after we had left the station. I then kept the PDA on (with non-backlit display) for the duration of the journey, which was 3 1/4 hours. So did it last the distance? At the start it was at 90% and by the end of that period, it had 50% battery left, which means only about 40% was used in that duration, which also included 3 quick calls and a 1 minute video shoot. All in all, quite impressive, I think!

There are quite a number of features in the ROM Upgrade that are worthy of mention, including support for receiving streaming video. However, now at my destination, I have about 2MB of GPS log to peruse... :-)

The more I hear about your PDA phone the more I want one, but I think I'll just have to wait until the prices become a bit more reasonable.

Something to mess with the GPS data?

I think the only 'reasonable' prices are with contracts. Worth being patient as occasionally there are some very good deals. Otherwise, for just the phone I think you'd need to pay somewhere between £350 and £370 at the moment, which actually is at a significant discount compared with a couple of months ago. Hope you can afford one soon!

Thanks for the link to GPS Visualiser.

I just got one from eBay for $450, about 310 euros, which is a reasonable price for the great phone. Htc website lists it for $699.

Just move around a little and you will find it cheap.

Worth mentioning is the new version, p3600i, with a 500Mhz processor and double the ROM memory.

Great post!
